Answer 2

1.) 3x²+10x = 12

Ans. 3x²+10x-12 = 0

3x²+10x+(-12) = 0

2.) -5x² = 3-8x

Ans. -5x²+8x-3 = 0

(-5x²)+8x+(-3) = 0

3.) 8x-3 = 4x²

Ans. 4x²-8x+3 = 0

4x²+(-8x)+3 = 0

4.) 12+5x-2x² = 0

Ans. (-2x²)+5x+12 = 0

5.) 2x(x-5) = 3

Ans. 2x²-10x-3 = 0

2x²+(-10x)+(-3) = 0

6.) x(3-5x)+12 = 0

Ans. 3x-5x²+12 = 0

(-5x²)+3x+12 = 0

7.) (x+2)(x+8) = 0

Ans. x²+8x+2x+16 = 0

x²+10x+16 = 0

8.) (x-3)(x-7) = 0

Ans. x²-7x-3x+21 = 0

x²+(-10x)+21 = 0

9.) (3x+2)(2x-4) = 0

Ans. 6x²-12x+4x-8 = 0

6x²+(-8x)+(-8) = 0

10.) 2(x-4)²+11 = 0

Ans. 2(x²+16-8x)+11 = 0

2x²+32-16x+11 = 0

2x²+(-16x)+21 = 0
