expand 3a^2(x+1)(x-1)

expand

3 a^{2} (x + 1) (x - 1)

3 a^{2} x^{2} - 3 a^{2}

Solution steps

3 a^{2} (x + 1) (x - 1)

Expand

3 a^{2} (x + 1) (x - 1) : 3 a^{2} (x^{2} - 1)

= 3 a^{2} (x^{2} - 1)

Apply the distributive law:

a (b - c) = ab - a c

3 a^{2} (x^{2} - 1) = 3 a^{2} x^{2} - 3 a^{2} \cdot 1

= 3 a^{2} x^{2} - 3 a^{2} \cdot 1

Multiply the numbers:

3 \cdot 1 = 3

= 3 a^{2} x^{2} - 3 a^{2}

(4^{\frac{2}{3}})^{3}

(2 x - 5) (x + 3)

(x^{2} + 2 x + 3)^{2}

(x - 2) (4 x^{2} + 2 x - 3)

(3 x + 2)^{2}
