Quadratic equations: factoring1.x^2-2x-24=02.2x^2+7x=153.6x^2+17x=3 ...

Step-by-step explanation:

1) x² - 2x - 24 = 0

(x - 6)(x + 4) = 0

x - 6 = 0

x = 6

x + 4 = 0

x = -4

2) 2x² + 7x = 15

2x² + 7x - 15 = 0

(2x - 3)(x + 5) = 0

2x - 3 = 0

2x = 3

x = 3/2

x + 5 = 0

x = - 5

3) 6x² + 17x. = 3

6x² + 17x - 3 = 0

(6x - 1)(x + 3) = 0

6x - 1 = 0

6x = 1

x = 1/6

x + 3 = 0

x = - 3
