2X^2-12=5X
2X^2-5X-12=0
(2X+3)(X-4)=0
2X+3=0
2X=-3
X=-3/2 OR -1.5 ANSWER.
X-4=0
X=4 ANSWER.
---------------------------------------------------------------
X^2-12=5X
X^2-5X-12=0
USING THE QUADRATIC EQUATIO -x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ WE GET: X=(5+-SQRT[-5^2-4*1*-12])/2*10
X=(5+-SQRT[25+48])/2
X=(5+-SQRT73)/2
X=(5+-8.544)/2
X=(5+8.544)/2
X=13.544/2
X=6.772 ANSWER.
X=(5-8.544)/2
X=-3.544/2
X=-1.772 ANSWER.
