5 - x^2 = (the square root of 5 minus x)(the square root of 5 plus x)
(x + 4)(x + 1)
5x2 + 20 = 5*(x2 + 4) which cannot be factorised further.
6x³ +12x + 18 = 6(x + 1)(x² - x + 3)
It is 3(2y+5) when factorised
5 - x^2 = (the square root of 5 minus x)(the square root of 5 plus x)
(x + 4)(x + 1)
5x2 + 20 = 5*(x2 + 4) which cannot be factorised further.
x - 5 is in its simplest form.
x2 + 4x + 3 = (x + 1)(x + 3)
6x³ +12x + 18 = 6(x + 1)(x² - x + 3)
x^2-x+1 cannot be factorised
It is 3(2y+5) when factorised
3x2+26x+16 When factorised: (3x+2)(x+8)
(-5 +/- sqrt(25 -24)) /2 = (-5 +/- 1)/2 = -2.5 +/- 0.5 = -2 or -3 Factorised (x + 3)(x + 2) which confirms answers above.
x2-9x+18 = (x-3)(x-6) when factorised
x2-6x+9 = (x-3)(x-3) when factorised.
