5x(3x + 1)
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
(x - 1)(5x + 7)
(5x - 2y)(5x + 2y)
5x = sqrt(10) + 15x -10x = sqrt(10) x = -sqrt(10)/10 = -sqrt(10)
5x(3x + 1)
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
5x
5x(x+3)
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
5(x2 + x + 1)
15
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
If that's 15x2, the answer is (3x + 4)(5x - 4)
x(x2+5x+6)
15x
