Best ResponseYou've already chosen the best response.1ok... do you know the differences of squares yet? as in \(\bf \textit{difference of squares} \\ \quad \\ (ab)(a+b) = a^2b^2\qquad \qquad a^2b^2 = (ab)(a+b)\)

Best ResponseYou've already chosen the best response.1ok... well then \(\bf \cfrac{5x12}{x^216}+\cfrac{8}{x^216} \\ \quad \\ {\color{brown}{ \cfrac{a}{b}+\cfrac{c}{b}\implies \cfrac{a+c}{b} }}\qquad thus \\ \quad \\ \cfrac{5x12}{x^216}+\cfrac{8}{x^216}\implies \cfrac{(5x12)+(8)}{x^216}\qquad {\color{brown}{ 16=4^2}}\qquad thus \\ \quad \\ \cfrac{5x128}{x^2{\color{brown}{ 4^2}}}\implies \cfrac{5x20}{(x4)(x+4)}\implies ?\)

Best ResponseYou've already chosen the best response.1notice the numerator you can take a common factor what do you think it is?

Best ResponseYou've already chosen the best response.1anyhow.. need to dash... as you can see, is 5, yes, for the common factor of the numerator thus \(\bf \cfrac{5x128}{x^2{\color{brown}{ 4^2}}}\implies \cfrac{5x20}{(x4)(x+4)}\implies \cfrac{5\cancel{(x4)}}{\cancel{(x4)}(x+4)}\)
