(5x - 3)(3x + 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!
No, 30 is a multiple of 15.
(x - 15)(x - 1)
The given expressions can be simplified to: 16x-10
It will be: 6x2 +8x -15

(2x - 5)(2x - 3)
No, 30 is a multiple of 15.
(x - 15)(x - 1)
The given expressions can be simplified to: 16x-10
It will be: 6x2 +8x -15
15x2 + 2x - 56 = 15x2 + 30x - 28x - 56 = 15x(x + 2) - 28(x + 2) = (15x - 28)(x + 2)
x+15=16x=16-15x=1
15x2 - 30x -720 = 15(x - 8)(x + 6).
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
15x2=30
X2 - 16X + 15 = 0 (X - 1)(X - 15) = 0 So X -1 = 0 or X - 15 = 0 ie X = 1 or X = 15
