simplify (x+2)(x-1)(x-sqrt(7))(x+sqrt(7))

simplify

(x + 2) (x - 1) (x - 7) (x + 7)

(x + 2) (x - 1) (x^{2} - 7)

Solution steps

(x + 2) (x - 1) (x - 7) (x + 7)

Apply Difference of Two Squares Formula:

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

(x - 7) (x + 7) = x^{2} - (7)^{2}

= (x + 2) (x - 1) (x^{2} - (7)^{2})

Simplify

x^{2} - (7)^{2} : x^{2} - 7

= (x + 2) (x - 1) (x^{2} - 7)

\frac{2 x ^{\frac{5}{3}} ( 4 t ^{2} - x )}{t ^{\frac{1}{3}}}

\frac{2 ( x + 1 )}{( 3 x + 7 ) ^{\frac{1}{3}}}

\frac{6 x ^{2}}{( 1 - 9 x ) ^{2}}

(3 + i)^{8}

(\frac{x}{6} - \frac{y}{8}) (\frac{x}{6} + \frac{y}{8})
