Solve 15 x + 79 - x^2 = x + 7

Evaluate

15 x + 79 - x^{2} = x + 7

Move the expression to the left side

14 x + 72 - x^{2} = 0

Factor the expression

More Steps

(18 - x) (4 + x) = 0

When the product of factors equals 0,at least one factor is 0

18 - x = 0 4 + x = 0

Solve the equation for x

More Steps

x = 18 4 + x = 0

Solve the equation for x

More Steps

x = 18 x = - 4

Solution

x_{1} = - 4, x_{2} = 18

15 x + 79 x^2 = x + 7
