Solve x^2-2x=60 - ScanMath

Evaluate

x^{2} - 2 x = 60

Move the expression to the left side

x^{2} - 2 x - 60 = 0

Substitute a= 1,b= - 2 and c= - 60 into the quadratic formula x = \frac{- b \pm b ^{2} - 4 a c}{2 a}

x = \frac{2 \pm ( - 2 ) ^{2} - 4 ( - 60 )}{2}

Simplify the expression

More Steps

x = \frac{2 \pm 244}{2}

Simplify the radical expression

More Steps

x = \frac{2 \pm 2 61}{2}

Separate the equation into 2 possible cases

x = \frac{2 + 2 61}{2} x = \frac{2 - 2 61}{2}

Simplify the expression

More Steps

x = 1 + 61 x = \frac{2 - 2 61}{2}

Simplify the expression

More Steps

x = 1 + 61 x = 1 - 61

Solution

x_{1} = 1 - 61, x_{2} = 1 + 61

Alternative Form

x_{1} \approx - 6.81025, x_{2} \approx 8.81025
