1x^2-6x+91X9 IS 9What multiplies to get 9 and adds to get -6? -3x-3So, (x-3)(x-3)
x2 - 6x - 27 = (x-9)(x+3)
x2-6x+9 = (x-3)(x-3) when factorised.
x^2-6x+9 (x-3)(x-3)
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
(4x - 3)(2x + 3)
1x^2-6x+91X9 IS 9What multiplies to get 9 and adds to get -6? -3x-3So, (x-3)(x-3)
x2 - 6x - 27 = (x-9)(x+3)
x2-6x+9 = (x-3)(x-3) when factorised.
(x^18 - 6x^9 + 18)(x^18 + 6x^9 + 18)
x^2-6x+9 (x-3)(x-3)
(x + 3)(x + 3)
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
(6x - 3)(x + 5) which becomes 3.(2x - 1)(x + 5)
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
3X2 + 6X + 9 3(X2 + 2 + 3) -----------------------3 is a common factor of all terms
Just looking at it, one factor is 3.
