(2x-5)(x+1)=2

Move all terms to the left side of the equation and simplify.
2x2−3x−7=0

Use the quadratic formula to find the solutions.
−b±√b2−4(ac)2a

Substitute the values a=2
, b=−3, and c=−7 into the quadratic formula and solve for x
3±√(−3)2−4⋅(2⋅−7)2⋅2

Simplify.
x=3±√654

The result can be shown in both exact and approximate form.
x=3±√654
x≈2.76556443,−1.26556443
