2x^2 + 13x + 15 factored means that the two numbers must multiply to the constant (15) and add to equal the coefficient on the X (13). So it becomes:
(2x + 3) (x + 5). If expanded, 2x*5 = 10x and 3 * x = 3x which add to 13x. And 5 * 3 = 15
2x2+13x+15 = (2x+3)(x+5)
vbh
6x2 + 13x + 2 = (6x + 1)(x + 2).
(3x + 2)(2x + 3)
The expression cannot be factorised.
2x2+13x+15 = (2x+3)(x+5)
x2 + 13x + 36 = (x + 9)(x + 4)
(x + 1)(3x + 10)
vbh
6x2 + 13x + 2 = (6x + 1)(x + 2).
3x2+13x-10 = (3x-2)(x+5) when factored
(x + 4)(x + 9)
(3x + 2)(2x + 3)
(x-4)
The expression cannot be factorised.
(x + 9)(x + 4)
(x + 10)(x + 3)
