What are the roots of the equation? x^2 − x − 42 = 0 Enter your answers in the boxes. X= X=

Answer 1

Answer:-6 or 7

Explanation:

Answer 2

x = -6 and x = 7

Explanation:

x² - x - 42 = 0

find two number which

a + b = -1

a*b = -42

a = -7

b = 6

x² - x - 42 = 0

(x-7)(x+6) = 0

x-7 = 0

x = 7

x +6 = 0

x = -6
