Question

Simplify: x squared minus 7x + 12 over x squared minus 16

- I got ( x-3 ) / ( x-4 )

Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow {x^2 - 7x - 12 \over (x + 4)(x - 4) } }\)

\(\Large \color{MidnightBlue}{\Rightarrow {x^2 - 4x - 3x - 12 \over (x + 4)(x - 4)} }\)

\(\Large \color{MidnightBlue}{\Rightarrow {(x - 3)(x - 4) \over (x + 4)(x - 4)} }\)

\(\Large \color{MidnightBlue}{\Rightarrow {(x - 3) \over (x + 4)} }\)

Answer 2

Got it?

Answer 3

Factored both numerator and denominator. Also, write the excluded values of x.
