Brahmagupta’s solution to a quadratic equation of the form ax2 bx = c involved only one solution. which solution would he have found for the equation 3x2 4x = 6?
The value of the quadratic equation is given by the formula. Then the value of x is 0.8968 and negative 2.23.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The equation for the expression is given below.
3x² + 4x = 6
3x² + 4x - 6 = 0
we know that the formula
[tex]\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Then we have
[tex]x = \dfrac{-4 \pm \sqrt{4^2-4*4*(-6)}}{2*3}\\\\x = \dfrac{-4 \pm \sqrt{112}}{6}\\\\x = 0.8968, \ -2.23[/tex]

Instructions: Use the image and your knowledge of the
isosceles triangle to find the value of x.
Answer:
Step-by-step explanation:
In Isosceles triangle base angles (angles oppoiste to equal sides) are congruent.
x + x + 98 = 180 {Angle sum proeprty of triangle}
2x + 98 = 180 {Subtract 98 from both sides}
2x = 180 - 98
2x = 82 {Divide both sides by 2}
x = 82/2
x = 41
Answer:
x = 41°
Step-by-step explanation:
An isosceles triangle has 2 opposite sides equal.
Therefore the angle opposite x is also x
Hence:
x + x + 98° = 180° (angles in a triangle add up to 180°)
2x + 98° = 180°
2x = 180° - 98°
2x = 82°
2x/2 = 82°/2
x = 41°

James and Sarah went out to lunch. The price of lunch for both of them was $60. They tipped their server 30% of that amount. How much did each person pay if they shared the price of lunch and the tip equally?
Answer:
The answer is that they both payed $9.00.
Step-by-step explanation:
The both payed $60.00, and 30% of that is $18.00.
( $60.00*.03=$18.00)
$18.00 divided by two (two people, James and Sarah) is $9.00.
So they both payed $9.00 individually.

Given line segment AB with endpoints A(-1, 7) and B(11, -1)
Find the length of AB
The length of the segment AB is the number of units on AB, and the length of segment AB is 14.4 units
How to determine the length of segment AB?The points are given as:
A = (-1,7)
B = (11,-1)
The length of the segment is then calculated using:
AB = √(x₁ - x₂)² + (y₁ - y₂)²
So, we have:
AB = √(-1 - 11)² + (7 + 1)²
Evaluate the exponent
AB = √144 + 64
Evaluate the sum
AB = √208
Evaluate the exponent
AB = 14.4
Hence, the length of segment AB is 14.4 units

Solve x^2=81 and x^2-18x=7.
Please show your work!
Answer:
x² = 81 , x = ± 9
x² - 18x = 7 : x = 9 ± √(22)
Step-by-step explanation:
x² = 81
simply take the square root of both sides
x = ± 9
x² - 18x = 7
This question is a bit more complicated as there is a variable with a power as well as a variable with no power. To solve for x we are going to have to put the equation in quadratic form then solve using the quadratic equation
x² - 18x = 7
put the equation in quadratic form by subtracting 7 from both sides so that the equation is equal to 0
x² - 18x - 7 = 0
we can now solve for x using the quadratic equation
recall the quadratic equation : [tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
where the value of a,b and c are derived from the equation
remember the equation is in quadratic form ax² + bx + c = 0
so ax² + bx + c = 0 : x² - 18x - 7 = 0
knowing this we can assign variables, a = 1 , b = -18 and c = -7
now we plug in the variables into the quadratic equation
recall equation : [tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
a = 1 , b = -18 and c = -7
plug in values
[tex]x=\frac{-(-18)+\sqrt{(-18)^2-4(1)(-7)} }{2(1)}[/tex]
remove parenthesis
[tex]x=\frac{18+\sqrt{(-18)^2-4(1)(-7)} }{2(1)}[/tex]
simplify exponent
[tex]x=\frac{18+\sqrt{324-4(1)(-7)} }{2(1)}[/tex]
simplify multiplication in square root and on denominator
[tex]x=\frac{18+\sqrt{324+28} }{2}[/tex]
simplify addition
[tex]x=\frac{18+\sqrt{352} }{2}[/tex]
simplify radical
