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

simplify

9 - 2 x 9 - 2 x^{2}

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

Solution steps

9 - 2 x 9 - 2 x^{2}

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

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

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

ln (\frac{x ^{2} - 9}{4 - x ^{2}})

lo g_{2} (8) - lo g_{2} (x) - lo g_{2} (y)

lo g_{10} (2) + lo g_{10} (3)

lo g_{10} (10 x)
