Solve (x-1-a)(x-1 a)

Evaluate

(x - 1 - a) (x - 1 \times a)

Any expression multiplied by 1 remains the same

(x - 1 - a) (x - a)

Apply the distributive property

x \times x - x a - x - (- a) - a x - (- a \times a)

Multiply the terms

x^{2} - x a - x - (- a) - a x - (- a \times a)

Multiply the terms

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

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

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

Solution
