Sagot :

x^2+4x-32=0

Rewrite the expression (Write 4x as a difference)

x^2+8x-4x-32=0

Factor the expression (Factor out x and -4 from the expression)

x(x+8)-4(x+8)=0

Factor the expression(Factor out x+8 from the expression)

(x+8)(x-4)=0

Separate into possible cases(When the product of factors equals 0 at least one factor is 0)

x+8=0

x-4=0

Solve the equation for x

x=-8

x=4

So that the equation has 2 solution

x1=-8

x2=4

note: x1=x sub 1

x2=x sub 2
