expand (4-5x)^2

Solution

expand

(4 - 5 x)^{2}

Solution

16 - 40 x + 25 x^{2}

Solution steps

(4 - 5 x)^{2}

Apply Perfect Square Formula:

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

(4 - 5 x)^{2} = 4^{2} - 2 \cdot 4 \cdot 5 x + (5 x)^{2}

= 4^{2} - 2 \cdot 4 \cdot 5 x + (5 x)^{2}

Simplify

4^{2} - 2 \cdot 4 \cdot 5 x + (5 x)^{2} : 16 - 40 x + 25 x^{2}

= 16 - 40 x + 25 x^{2}
