X^2+6X+10=2X+2X^2
X^2-2X^2+6X-2X+10=0
-X^2+4X+10=0
X^2-4X-10=0
USING THE QUADRATIC EQUATION x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ WE GET:
X=(4+-SQRT[-4^2-4*1*-10])/2*1
X=(4+-SQRT[16+40])/2
X=(4+SQRT56)/2
X=(4+-7.48)/2
X=(4+7.48)/2
X=11.48/2
X=5.74 ANSWER.
X=(4-7.48)/2
X=-3.48/2
X=1.74 ANSWER.
