expand (-2x+5)^2

Solution

expand

(- 2 x + 5)^{2}

Solution

4 x^{2} - 20 x + 25

Solution steps

(- 2 x + 5)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(- 2 x)^{2} + 2 (- 2 x) \cdot 5 + 5^{2} : 4 x^{2} - 20 x + 25

= 4 x^{2} - 20 x + 25
