Question

(x-4)(x+2) =0 by factorization method
​

Answer 1

Answer:

$(x - 4)(x + 2) = 0$

$x(x + 2) - 4(x + 2) = 0$

$x {}^{2} + 2x - 4x - 8 = 0$

$x {}^{2} - 2x - 8 = 0$

Answer 2

Answer:

x=4,-2

Step-by-step explanation:

x-4*x+2=0

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

x^2-2x-8=0

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

x(x-4)+2(x-4)=0

x-4=0;x+2=0

x=4;x=-2

x=4,-2
