expand (a+b)^2-4c^2

expand

(a + b)^{2} - 4 c^{2}

a^{2} + 2 ab + b^{2} - 4 c^{2}

Solution steps

(a + b)^{2} - 4 c^{2}

Apply Perfect Square Formula:

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

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

= a^{2} + 2 ab + b^{2} - 4 c^{2}

(- 2 e^{- x})^{2}

i^{145}

- (x + 5)^{3}

x - 2 \cdot x - 2

36 + 25
