Solve x^2 + 4x + 4 = 9

Evaluate

x^{2} + 4 x + 4 = 9

Move the expression to the left side

x^{2} + 4 x - 5 = 0

Factor the expression

More Steps

(x - 1) (x + 5) = 0

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

x - 1 = 0 x + 5 = 0

Solve the equation for x

More Steps

x = 1 x + 5 = 0

Solve the equation for x

More Steps

x = 1 x = - 5

Solution

x_{1} = - 5, x_{2} = 1

X^2 + 4x + 4 = 9
