expand (9g-4)^2

Solution

expand

(9 g - 4)^{2}

Solution

81 g^{2} - 72 g + 16

Solution steps

(9 g - 4)^{2}

Apply Perfect Square Formula:

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

(9 g - 4)^{2} = (9 g)^{2} - 2 \cdot 9 g \cdot 4 + 4^{2}

= (9 g)^{2} - 2 \cdot 9 g \cdot 4 + 4^{2}

Simplify

(9 g)^{2} - 2 \cdot 9 g \cdot 4 + 4^{2} : 81 g^{2} - 72 g + 16

= 81 g^{2} - 72 g + 16
