simplify 5*(x+7+sqrt(149))(x+7-sqrt(149))

simplify

5 \cdot (x + 7 + 149) (x + 7 - 149)

5 x^{2} + 70 x - 500

Solution steps

5 (x + 7 + 149) (x + 7 - 149)

Expand

(x + 7 + 149) (x + 7 - 149) : x^{2} + 14 x - 100

= 5 (x^{2} + 14 x - 100)

Expand

5 (x^{2} + 14 x - 100) : 5 x^{2} + 70 x - 500

= 5 x^{2} + 70 x - 500

\frac{- x + 1}{( x + 1 ) ^{3}}

(u + i)^{4}

f (- 2) + g (2)

2 \cdot (arcsin (1 - x^{2}) + ∣ arcsin (x) ∣)

\frac{1}{( x + 3 ) ( x - 3 )}
