(2x+1)(2x+3) when factored
3x2-39x-90 = (3x+6)(x-15) when factored
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
It cannot be factored because the discriminant of b2-4ac is less than zero.
Yes, 15 + 15 = 30
2s2+7s-15 = (2s-3)(s+5) when factored
(2x+1)(2x+3) when factored
3x2-39x-90 = (3x+6)(x-15) when factored
h2 -16h+15 = (h -1)(h -15) when factored
2x2 + 7x - 15 = (2x - 3)(x + 5)
Oh, dude, it's like this - you gotta find two numbers that multiply to -225 (15 * -15) and add up to 16. So, the numbers are 25 and -9. Then you can rewrite the equation as (5x + 25)(3x - 9). And that's how you factor it, easy peasy!
X2 - 8X + 15 = (X - 3)(X - 5)
x2+2x-15 = (x+5)(x-3) when factored
It is a quadratic expression and is (x-3)(x+5) when factored
If you mean m^2 -8m +15 then it equals (m -3)(m -5) when factored
25 plus 52 plus 15 is equal to 92.
