Solve w^2-39w-126=0

Evaluate

w^{2} - 39 w - 126 = 0

Factor the expression

More Steps

(w - 42) (w + 3) = 0

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

w - 42 = 0 w + 3 = 0

Solve the equation for w

More Steps

w = 42 w + 3 = 0

Solve the equation for w

More Steps

w = 42 w = - 3

Solution

w_{1} = - 3, w_{2} = 42
