Question

X^2+13x-12=0 what is the solutions

Answer 1

use the quadratic formula, we must.

$-b +/- \frac{\sqrt{b^2 - 4ac} }{2a}$

-13 +/- √(169 +48) / 2

-13 +/- √217 / 2

-13 +/- 14.73 / 2

(-13 + 14.73) / 2 = 0.865

(-13 - 14.73) / 2 = -13.865

the solutions, we have found.

helped, i hope i have.
