expand (x+h-1)^2

Solution

expand

(x + h - 1)^{2}

Solution

x^{2} + 2 x h - 2 x + h^{2} - 2 h + 1

Solution steps

(x + h - 1)^{2}

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

(x + h - 1)^{2} = (x + h - 1) (x + h - 1)

= (x + h - 1) (x + h - 1)

Distribute parentheses

= xx + x h + x (- 1) + h x + hh + h (- 1) - 1 \cdot x - 1 \cdot h - 1 \cdot (- 1)

Simplify

xx + x h + x (- 1) + h x + hh + h (- 1) - 1 \cdot x - 1 \cdot h - 1 \cdot (- 1) : x^{2} + 2 x h - 2 x + h^{2} - 2 h + 1

= x^{2} + 2 x h - 2 x + h^{2} - 2 h + 1
