expand (3x+1)(3x-1)x

expand

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

3 x^{2} (3 x + 1)^{\circ} - x (3 x + 1)^{\circ}

Solution steps

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

= x (3 x - 1) (3 x + 1)^{\circ}

Apply the distributive law:

a (b - c) = ab - a c

a = (3 x + 1)^{\circ} x, b = 3 x, c = 1

= (3 x + 1)^{\circ} x \cdot 3 x - (3 x + 1)^{\circ} x \cdot 1

= 3 xx (3 x + 1)^{\circ} - 1 \cdot x (3 x + 1)^{\circ}

Simplify

3 xx (3 x + 1)^{\circ} - 1 \cdot x (3 x + 1)^{\circ} : 3 x^{2} (3 x + 1)^{\circ} - x (3 x + 1)^{\circ}

= 3 x^{2} (3 x + 1)^{\circ} - x (3 x + 1)^{\circ}

v (\frac{( 1 + v ^{2} ) ^{5}}{5} - v^{9})

\frac{x y \cdot ( 32 - x y )}{( x + y )}

3 (t - \frac{π}{4})

(x^{2}) (x^{3} - 5 e^{- 2 x} - 2 x^{\frac{1}{2}})

(1 + a) (1 - a)
