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

simplify

2 \cdot x + 1 \cdot x - 1

2 (x + 1) (x - 1)

Solution steps

2 x + 1 x - 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 1 x - 1 = (x + 1) (x - 1)

= 2 (x + 1) (x - 1)

1318 \cdot (1.052)^{- 19}

1 0^{9} (1 \cdot 1 0^{- 12})

(- 2 5^{- 4})^{- 7} \cdot (- 62 5^{- 4})^{4} \cdot (\frac{1}{5})^{- 8}

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

(2 x) (5 x^{3})
