√41 or x=

+

1

4

√41

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2x2+x=−5

Step 2: Subtract -5 from both sides.

−2x2+x−(−5)=−5−(−5)

−2x2+x+5=0

For this equation: a=-2, b=1, c=5

−2x2+1x+5=0

Step 3: Use quadratic formula with a=-2, b=1, c=5.

x=

−b±√b2−4ac

2a

x=

−(1)±√(1)2−4(−2)(5)

x=
