simplify (x+1+sqrt(10))(x+1-sqrt(10))

simplify

(x + 1 + 10) (x + 1 - 10)

x^{2} + 2 x - 9

Solution steps

(x + 1 + 10) (x + 1 - 10)

Distribute parentheses

= xx + x \cdot 1 + x (- 10) + 1 \cdot x + 1 \cdot 1 + 1 \cdot (- 10) + 10 x + 10 \cdot 1 + 10 (- 10)

Simplify

xx + x \cdot 1 + x (- 10) + 1 \cdot x + 1 \cdot 1 + 1 \cdot (- 10) + 10 x + 10 \cdot 1 + 10 (- 10) : x^{2} + 2 x - 9

= x^{2} + 2 x - 9

(\frac{4 x ^{2} y}{3} + y) (\frac{2 x ^{4} y ^{2}}{5} + 2)

(2 - 47) \cdot (23 - 5)

e^{x} (x - 4)

(3 x + 2) 2 x + 1
