Question

What are the solutions of the equation x^2 + 14x = -130?

A. 2, –16
B. 10, –13
C. –2, 16
D. No Solution

Answer 1

Can you show me how to solve for the answers?

Answer 2

\[x ^{2} + 14x = -130\]

Answer 3

it's good to know alternate and quick methods sometimes.

Substitute each pair values to see if they = -130

Answer 4

add 130 to both sides. Now use discriminant b^2 - 4ac, for ax^2 +bx + c. Remember that when this is less than 0, there are no real solutions. This is the case for this quadratic, since 14^2< 4*130
