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

simplify

x - 7 \cdot x + 1

(x - 7) (x + 1)

Solution steps

x - 7 x + 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

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

= (x - 7) (x + 1)

\frac{1875.3944 1 ^{2}}{1239.842} \cdot 5.79 \cdot 1 0^{- 5}

e^{- A t}

- 5 e^{- 3 x} (- sin^{2} (x) + cos (x) (3 - cos (x)))

\frac{9 9 ^{100}}{10 0 ^{100}}

e^{- 0.003 \cdot 50}
