expand (x-a)^2-b^2

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

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

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

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

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