simplify (a+x)^2-(x+2)^2

Solution

simplify

(a + x)^{2} - (x + 2)^{2}

Solution

a^{2} + 2 a x - 4 x - 4

Solution steps

(a + x)^{2} - (x + 2)^{2}

Expand

(a + x)^{2} : a^{2} + 2 a x + x^{2}

= a^{2} + 2 a x + x^{2} - (x + 2)^{2}

Expand

- (x + 2)^{2} : - x^{2} - 4 x - 4

= a^{2} + 2 a x + x^{2} - x^{2} - 4 x - 4

Add similar elements:

x^{2} - x^{2} = 0

= a^{2} + 2 a x - 4 x - 4
