expand (3ax-1)^2

Solution

expand

(3 a x - 1)^{2}

Solution

9 a^{2} x^{2} - 6 a x + 1

Solution steps

(3 a x - 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= 9 a^{2} x^{2} - 6 a x + 1
