Jeremy solved the equation LaTeX: x^2-x-42=0x 2 − x − 42 = 0 by factoring.

Part B: Which of the following are the solutions to LaTeX: x^2-x-42=0x 2 − x − 42 = 0 ?

Respuesta :

Answer:

x = 7, -6.

Step-by-step explanation:

x^2 - x - 42 = 0

x^2 - 1x - 42 = 0

Now -42 = 6 * -7 and 6 - 7 = -1, so we have:

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

x = 7, -6.
