simplify sqrt(x+4)*sqrt(x-5)

simplify

x + 4 \cdot x - 5

(x + 4) (x - 5)

Solution steps

x + 4 x - 5

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 4 x - 5 = (x + 4) (x - 5)

= (x + 4) (x - 5)

1 + x^{2} \times 1 - x^{2}

((2^{5})^{2})^{4}

e^{- 3} (- \frac{2}{2} - 1)

\frac{1}{2} \cdot 0.3 2^{2} \cdot 0.5 2^{- 2}
