Please help with the math problem by showing the steps to solve it.

Solve the equation:

\[ x^2 - 13x = -36 \]

Asked by renjac1301

Answer (2)

x^2 - 13 x = -36 add 36 to both sides
x^2 - 13x +36 = 0 figure out the factor (x-4)(x-9) = 0 so (x-4) or (x-9) equals 0 so solution is x-4=0 add 4 to both sides and get x = 4 x-9=0 add 9 to both sides and get x=9 x={ 4, 9}

To solve the equation x 2 − 13 x = − 36 , first rearrange it to x 2 − 13 x + 36 = 0 . Then factor it as ( x − 4 ) ( x − 9 ) = 0 and solve for x , giving solutions x = 4 and x = 9 .
