Answer:

1.

x² + 5x = 0

x × (x+5) = 0

x = 0 , x + 5 = 0

x = 0 , x -5

2.

7x² + 21x = 0

7x × (x+3) = 0

x × (x+3) = 0

x = 0 , x + 3 = 0

x = 0 , x = -3

3.

16x² = 12x

4x² = 3x

4x² - 3x = 0

x× (4x - 3) = 0

x = 0 , 4x - 3 = 0

x = 0 , x = 3/4

4.

-4x = 6x

2x² = - 3x

2x² + 3x = 0

x × (2x + 3) = 0

x = 0 , 2x + 3 = 0

x = 0, x = -3/2

5.

x² + 8x + 12=0

x² + 6x + 2x + 12 = 0

x × (x+6) + 2x + 12 = 0

x × (x+6) + 2 (x + 6) = 0

(x+6) × (x+2) = 0

x + 6 = 0 , x + 2 = 0

x = -6 , x + 2 = 0

x = -6 , x = -2
