simplify sqrt(9-x^2)*sqrt(x+2)

simplify

9 - x^{2} \cdot x + 2

(x + 2) (- x^{2} + 9)

Solution steps

9 - x^{2} x + 2

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

- x^{2} + 9 x + 2 = (- x^{2} + 9) (x + 2)

= (- x^{2} + 9) (x + 2)

e^{(- l n (y))}

2.65 \cdot 1 0^{- 2}

7.62 \cdot 1 0^{- 5}

e^{- 2 (- t + 1)} u (- t + 1)

2.75 \cdot 1 0^{- 3}
