x^2+18=9x

OpenStudy (campbell_st):

rewrite it as \[x^2 - 9x + 18 = 0\] this is now a quadratic equation that can be factored. hope it helps

OpenStudy (anonymous):

yeah but i want it to be factored

OpenStudy (campbell_st):

well what are the factors of 18 that add to -9... both factors are negative...

OpenStudy (anonymous):

6 and 3

OpenStudy (campbell_st):

well if that's you solution you're correct. . (x - 6)(x - 3) = 0 so you solve x - 6 = 0 and x - 3 = 0

OpenStudy (anonymous):

x=6 and x=3

OpenStudy (campbell_st):

that's correct
