To solve the quadratic equation
by factoring, we need to find two numbers that multiply to
and add up to
.The quadratic equation is in the form
, where
,
, and
.We need to find two numbers whose product is \(ac = 1 \cdot (-32) = -32\) and whose sum is
.The numbers that satisfy these conditions are
and
, because:
So, we can factor the quadratic equation as:
Setting each factor equal to zero gives us the solutions:
Solving these equations, we get:
Therefore, the solutions to the equation
are:
