expand (3x^2+1)^2

Solution

expand

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

Solution

9 x^{4} + 6 x^{2} + 1

Solution steps

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

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

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

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

Simplify

(3 x^{2})^{2} + 2 \cdot 3 x^{2} \cdot 1 + 1^{2} : 9 x^{4} + 6 x^{2} + 1

= 9 x^{4} + 6 x^{2} + 1
