Question

What is X squared +3x-70

Answer 1

Answer:

x = 7, x = -10

Step-by-step explanation:

$x^2+3x-70 = 0$

Use the quadratic formula.

$x = \frac{-3 + \sqrt{3^2-4(1)(-70)} }{2(1)} \\x = \frac{-3 - \sqrt{3^2-4(1)(-70)} }{2(1)}$

Solve.

x = 7, x = -10

You can also factor if you want - that is a faster method.
