Solve x^2-x-57 - ScanMath

Evaluate

x^{2} - x - 57

To find the roots of the expression,set the expression equal to 0

x^{2} - x - 57 = 0

Substitute a= 1,b= - 1 and c= - 57 into the quadratic formula x = \frac{- b \pm b ^{2} - 4 a c}{2 a}

x = \frac{1 \pm ( - 1 ) ^{2} - 4 ( - 57 )}{2}

Simplify the expression

More Steps

x = \frac{1 \pm 229}{2}

Separate the equation into 2 possible cases

x = \frac{1 + 229}{2} x = \frac{1 - 229}{2}

Solution

x_{1} = \frac{1 - 229}{2}, x_{2} = \frac{1 + 229}{2}

Alternative Form

x_{1} \approx - 7.066373, x_{2} \approx 8.066373
