Question

PLEASE HELP!
Solve x2 - 7x = -13.

Answer 1

x^2 - 7x = -13

x^2 - 7x + 13 = 0

now use the quadratic formula with these values

a = 1
b = -7
c = 13

Answer 2

@jim_thompson5910 i just dont understand this quadratic equation stuff at all

Answer 3

@jim_thompson5910 i think i may have figured it out!
is it the last option?

Answer 4

\[\Large x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]
\[\Large x = \frac{-(-7) \pm \sqrt{(-7)^2 - 4(1)(13)}}{2(1)}\]
\[\Large x = \frac{7 \pm \sqrt{-3}}{2}\]
yes it leads to the last answer choice
