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

simplify

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

- x x^{2} - 9

Solution steps

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

Apply rule:

(a) = a

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

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

Apply rule:

a (- b) = - ab

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

= - x^{2} - 9 x

= - x x^{2} - 9

5 (3 + 2)

sin (x) (sin (3 x) + sin (5 x))

\frac{( - x + 1 ) ^{3}}{3}

50

\frac{12 ( 3 - 5 )}{5}
