Determine whether the polynomial is a difference of squares and if it is, factor it.
GREYUIT [131]
Remember these three formulas (really, learn these by heart):

{(a + b)}^{2}  =  a^{2} + 2ab +  b^{2}

{(a - b)}^{2} = a^{2} - 2ab + b^{2}

(a + b)(a - b) = a^{2} - b^{2}

The stated formula is a manifestation of the last of these three. So indeed,

(y + 15)(y - 15) = y^{2} - 225

Let f(x)=6x. The graph of f(x) is transformed into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 uni
hram777 [196]
K so a translation of 2 units up is just adding 2 to the end of the equation, and a vertical compression of 1/3 means dividing the slope by 3:
so your equation goes from

f(x)=6x (compresses to)
2x (add 2 for the translation)
g(x)=2x+2

Hope this helped.
