Solve (-x/25)^2 - x/10 + 21 = 0

Evaluate

(- \frac{x}{25})^{2} - \frac{x}{10} + 21 = 0

Multiply both sides of the equation by LCD

((- \frac{x}{25})^{2} - \frac{x}{10} + 21) \times 1250 = 0 \times 1250

Simplify the equation

More Steps

2 x^{2} - 125 x + 26250 = 0 \times 1250

Any expression multiplied by 0 equals 0

2 x^{2} - 125 x + 26250 = 0

Substitute a= 2,b= - 125 and c= 26250 into the quadratic formula x = \frac{- b \pm b ^{2} - 4 a c}{2 a}

x = \frac{125 \pm ( - 125 ) ^{2} - 4 \times 2 \times 26250}{2 \times 2}

Simplify the expression

x = \frac{125 \pm ( - 125 ) ^{2} - 4 \times 2 \times 26250}{4}

Simplify the expression
