factor (x^2+4x-21)/(x+7)

factor

\frac{x ^{2} + 4 x - 21}{x + 7}

x - 3

Solution steps

\frac{x ^{2} + 4 x - 21}{x + 7}

Factor

x^{2} + 4 x - 21 : (x - 3) (x + 7)

= \frac{( x - 3 ) ( x + 7 )}{x + 7}

Cancel the common factor:

x + 7

= x - 3

w^{8} - 35 w^{4} + 304

1 + (x^{3} - 2 x^{2})

x^{2} + 1 - 6 + 6

m p + m q + n p + n q
