expand (8x-7)^2

Solution

expand

(8 x - 7)^{2}

Solution

64 x^{2} - 112 x + 49

Solution steps

(8 x - 7)^{2}

Apply Perfect Square Formula:

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

(8 x - 7)^{2} = (8 x)^{2} - 2 \cdot 8 x \cdot 7 + 7^{2}

= (8 x)^{2} - 2 \cdot 8 x \cdot 7 + 7^{2}

Simplify

(8 x)^{2} - 2 \cdot 8 x \cdot 7 + 7^{2} : 64 x^{2} - 112 x + 49

= 64 x^{2} - 112 x + 49
