expand (12)/((x+4)(x-3))

expand

\frac{12}{( x + 4 ) ( x - 3 )}

\frac{12}{x ^{2} + x - 12}

Solution steps

\frac{12}{( x + 4 ) ( x - 3 )}

Expand

(x + 4) (x - 3) : x^{2} + x - 12

= \frac{12}{x ^{2} + x - 12}

(x + 4 + \frac{4}{x}) x^{2}

(- y + 3)^{2}

(cos (2) (x - 1)) - 1

(1 + tan (x) + sec (x)) (1 + cot (x) - csc (x))
