User: x2 - 2(x - y);x = 6 and y = 2

Weegy: x2 - x - 90 = 0 in factored form is (x-10)(x+9)=0

User: -2[7x - 7 - 6(x + 1)] = 2x + 5

User: -(4x - 5)

Weegy: it is a special factor (a-b)(a+b) = a^2 - b^2 a=7y b=(4-4x) so the answer is 49y^2- (4-4x)^2 simplify it it will be 49y^2- 16 +32x -16x^2 rearange it , it will be 49y^2 - 16x^2 +32x-16

User: What is the "slope-intercept" format of the equation of a line?

Weegy: The equation is Y = Mx + B. In this equation, m is the slope value and B is the y intercept. X and Y are coordinates of the line which can be substituted into the equation to solve for other variables. Example of equation: Y = 3x + 7.

when x = 6 and y = 2,
x2 - 2(x - y)
= 36 - 2(6-2)
= 36 - 8
= 28

-2[7x - 7 - 6(x + 1)] = 2x + 5
-2(7x - 7 - 6x - 6) = 2x + 5
-2(x - 13) = 2x + 5
-2x + 26 = 2x + 5
4x = 21
x = 21/4
