X\Xb2-X-6=0, X\Xb2+5x+6=0, 2x\Xb2+3x+1=0

X²-x-6=0
X²+5x+6=0
2x²+3x+1=0

 

{x}^{2} - x - 6 = 0

(x + 2)(x - 3) = 0

x + 2 = 0 or x - 3 = 0

x = -2 or x = 3

{x}^{2} + 5x + 6 = 0

(x + 2)(x + 3) = 0

x + 2 = 0 or x + 3 = 0

x = -2 or x = -3

{2x}^{2} + 3x + 1 = 0

(2x + 1)(x + 1) = 0

2x + 1 = 0 or x + 1 = 0

x = -1/2 or x = -1

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
