Assuming that what you're looking for is the values of x:
x2 + 7x = 8
x2 + 7x - 8 = 0
(x + 8)(x - 1) = 0
x is equal to either -8 or 1.

What is x2 plus 7x-8?
x2+7x-8 = (x-1(x+8)
What is x2 7x-8?
x2+7x-8 = (x-1(x+8)
What are the steps for 7x plus 8 equals 36?
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
8 plus 7x equals 20 plus 3x what is x?
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
-8 plus 7x equals x-50?
-8 + 7x = x - 506x = -42x = -6
X2 plus 7x -8?
x2 + 7x - 8 = (x + 8)(x - 1)
What is x2 plus 7x-8?
x2+7x-8 = (x-1(x+8)
What are the points of intersection of the curves y equals x2 -7x plus 8 and y equals -x2 plus 9x -6 showing work?
If: y = x2-7x+8 and y = -x2+9x-6 Then: x2-7x+8 = -x2+9x-6 So: 2x2-16x+14 = 0 => x2-8x+7 = 0 Therefore: x = 1 and x = 7 By substitution: x =1, y = 2 and x = 7, y = 8 Points of intersection: (1, 2) and (7, 8)
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
What is x2 7x-8?
x2+7x-8 = (x-1(x+8)
What is the answer to 5x plus 8 equals 7x?
7x-5x=8 2x=8 x=4
What is x squared-7x equals 8 factored?
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
What are the steps for 7x plus 8 equals 36?
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
What is the answer to 7x plus 13x plus 2x plus 8 equals?
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
8 plus 7x equals 20 plus 3x what is x?
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
-8 plus 7x equals x-50?
-8 + 7x = x - 506x = -42x = -6
4x plus 5 equals 7x-8?
4x+5=7x-8 the ansewr is 3.25
