simplify sqrt(x-2)*sqrt(x+7)

simplify

x - 2 \cdot x + 7

(x - 2) (x + 7)

Solution steps

x - 2 x + 7

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x - 2 x + 7 = (x - 2) (x + 7)

= (x - 2) (x + 7)

e^{- t} sin (wt + θ)

k e^{- a t} cos (wt)

\frac{x ^{3}}{( 5 x - 2 ) ^{3}}

(a^{3} b^{4} c^{5}) (a b^{3} c)
