(x + 15)(x - 3)
5(x^2 + 9)
x2 + 14x + 45 = (x + 9) (x + 5)
is 28x squared? if it is, the answer would be, 3(2x+5)(4x+3).
The highest common factor of 15 and 45 is 15
(4k + 5)(5k - 9)
15v2+52v+45 = (5v+9)(3v+5) when factord
x2 + 18x + 45 = (x + 15)(x + 3).
(x+3)(x+15)
5(4x + 9)
(z + 15)(z + 3)
4y - 3
x2 - 14x + 45 = (x - 5)(x - 9).
