Question

Solve using perfect square factoring patterns.

x^2 – 12x + 36 = 4


{–8, –4}
{–2, 10}
{4, 8}
{10, –2}

Answer 1

You can Express equation
(X-6)^2 = 2^2

Answer 2

x^2-12x+36 = 4
group the like term
x^2-12x+36 -4 = 0
x^2-12x+32
factories the term of equation
x^2-8x-4x+32 = 0
x(x-8)-4(x-8) = 0
(x-8) (x-4) = 0
x-8 = 0, x-4 = 0
x = 8, x =4
the solution is {4,8}
