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)
5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.
8x^2 + 14x + 3 factors to (4x + 1)(2x + 3)

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)
5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.
(x - 2)(5x + 24)
5x2 + 14x - 3 let 14x = 15x - x=5x 2 + 15x - x - 3 factor out 5x and -1 = 5x(x + 3) - 1(x + 3) factor (x + 3) = (x + 3)(5x - 1)
8x^2 + 14x + 3 factors to (4x + 1)(2x + 3)
Improved answer:5x2+14x+5 = 5-5x2+14x+5 = 0Solve by completing the square:(x+7)2+5 = 0(x+7)2+5-49 = 0(x+7)2 = 44x+7 = + or - the square root of 44x = -7 + or - the square root of 44
5x2 + 3x - 1 does not have rational factors.

5x2-18x+9 = (5x-3)(x-3)
It is: 2xsquared+14x-9
