h, g, f, e, d, c, b,
a
6.) (X+)(X-7)=-3x 7.) (X-4)^2+8=0 8.) (X+2)^2 = (X+)^2 9.) (2x-1)^2=(X+1)^2 10.) 2x(X-4)= (X-3) (X-3)
6.) (x+)(x-7)=-3x 7.) (x-4)^2+8=0 8.) (x+2)^2 = (x+)^2 9.) (2x-1)^2=(x+1)^2 10.) 2x(x-4)= (x-3) (x-3) Answer: 9. (2x-1)^2 = (x + 1)^2 (2x - 1)(2x - 1) = (x+1)(x+1) 4x^2 - 2x - 2x +1 = x^2 + x + x + 1 4x^2 - 4x + 1 = x^2 + 2x + 1 4x^2 - x^2 - 4x - 2x + 1 - 1 = 0 3x^2 - 6x = 0 10. 2x(x-4)=(x-3)(x-3) 2x^2 - 8x = x^2 - 3x - 3x + 9 2x^2 - 8x = x^2 - 6x + 9 2x^2 - x^2 - 8x + 6x - 9 = 0 x^2 - 2x - 9 = 0
