Question

Solve by factoring y=4x^2-24x+36

Answer 1

(x-3) (x-3)

Explanation:

`4x {}^(2) - 24x + 36 \\ dividing \: through \: by \: 4 \\ x {}^(2) - 6x { }^{} + 9 \\ two \: numbers \: such \: that \: when \: you \: add \: them \: they \: give \: you \: - 6 \: and \: when \: you \: multiply \: them \: they \: give \: 9 \\ the \: numbers \: are \: \: - 3 \: and \: - 3 \\ x {}^(2) - 3x - 3x + 9 \\ x( x - 3) - 3(x - 3) \\ (x - 3)(x - 3)`
