Question

X^2-12x+36=0

X=

Solve for x

Answer 1

Explanation:

X^2-12x+36=0

X^2 - 8x - 4x + 36 = 0

(x^2 -8x) - (4x - 36) = 0

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

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

:- x - 4 = 0 or x - 8 = 0

x = 4 or x = 8

Answer 2

x = 6 (Multiplicity 2).

Explanation:

x^2 - 12x + 36 = 0

(x - 6)(x - 6) = 0

x = 6.
