Homework Help: Algebra

Posted by John on Monday, November 12, 2007 at 10:35pm.

Hello all - I would like to check my work on 2 problems.
Solve by factoring :
x^2-13x= -12
x^2-13x+12= -12 + 12
x^2-13x+12= 0
(x-1)(x-12)= 0
x = 1 , 12

Solve using the square root property:
2x^2-35=15
2x^2-35-15=0
2x^2-50=0
2(x-5)(x+5)=0
x = 5 , -5 Not sure I did this one right.
