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

simplify

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

x^{2} - 2 x - 6

Solution steps

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

Distribute parentheses

= xx + x (- 1) + x 7 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 7 - 7 x - 7 (- 1) - 77

Simplify

xx + x (- 1) + x 7 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 7 - 7 x - 7 (- 1) - 77 : x^{2} - 2 x - 6

= x^{2} - 2 x - 6

\frac{n ^{2} ( n + 3 ) ^{3}}{2}

\frac{( cos ( x ) + 1 )}{( x - π ) ^{2}}

\frac{s ( 3 s ^{2} + 4 s + 1 )}{s ^{2} + 2}

(y^{2} + \frac{5}{2}) (y^{2} - \frac{3}{2})

(- \frac{x ^{3}}{4} + 2 y) \cdot (3 x^{2} - x y + y^{4})
