x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
x(x2+5x+6)
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
The GCF is 5x
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
It is: 5x
(x + 5)(x + 8)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
5x
-15x2+5x=-5x(3x-1)
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
5(x2 + x + 1)
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
One factor of 6x² + 5x - 11 is (x - 1).
x(x2+5x+6)
(x - 5)(5x - 7)
(6 - 5x)(6 - 5x)
