7x2+49x+84 = 0

Divide all terms by 7:

x2+7x+12 = 0

Factorize:

(x+3)(x+4) = 0

Therefore the x intercepts are -3 and -4

It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.

It is a quadratic expression and it is (7x+6)(7x+6) when factored

49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
