If that's 15x2, the answer is (3x + 4)(5x - 4)
(y + 8)(y - 2)
In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
Since 16 is a factor of 32, it is automatically the GCF.
The greatest factor of 21 and 16 is 21, which is a factor of 21 but not of 16.
4x + 16 + 1 = 4x + 17 which cannot be factorised.
-((x + 2)(x - 8))
4d2+16 4(d2+4)
(g - 16)(g - 16) or (g - 16)2
x^2 + 10x + 16 = (x + 8)(x + 2)
(3x + 4)(3x + 4)
4(x + 2)(x + 2)
4(y + 2)(y + 2)
x + 4
4(3y+4)
4(y + 2)(y + 2)
(b + 4)(b + 4)
