2x^2-5x=-7
---
2x^2-5x+7 = 0
---
2x^2-7x+2x+7 = 0
x(2x-7)+(2x+7) = 0
(2x-7)(x+1) = 0
x = 7/2 or x = -1
need the solution set= {7/2 , -1}

2x^2-5x=-7
2X^2-5X+7=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
X=(5+-SQRT[-5^2-4*2+7])/2*2
X=(5+-SQRT[25-56])/4
X=(5+-SQRT-31)/4
X=(5+-5.568i)/4
X=5/4+-1.39i ANS.
(1.25+1.39i,1.25-1.39i)
