(x + 2)(x + 1)
3x^2 -14x +15 = (3x-5)(x-3)
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
(x + 2)(3x - 1)(3x + 1)
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
It is a quadratic expression and can be factored into: (3x+1)(x+2)
(3x - y+ 2)(3x + y + 2)
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
(3x - 2)(x + 8)
(3x + 3y)(x + y) = 3(x + y)2

3x^2 -14x +15 = (3x-5)(x-3)
(x^2 - 3x + 5)(x^2 + 3x + 5)
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
2(5x - 1)(3x - 2)
(x + 2)(3x - 1)(3x + 1)
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
(x - 2)(2x + 7)
