Solve (a b)^2 ( a - b )^2

Evaluate

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

Evaluate the power

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

Evaluate the power

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

Apply the distributive property

a^{2} b^{2} a^{2} - a^{2} b^{2} \times 2 ab + a^{2} b^{2} \times b^{2}

Multiply the terms

More Steps

a^{4} b^{2} - a^{2} b^{2} \times 2 ab + a^{2} b^{2} \times b^{2}

Multiply the terms

More Steps

a^{4} b^{2} - 2 a^{3} b^{3} + a^{2} b^{2} \times b^{2}

Solution

More Steps

a^{4} b^{2} - 2 a^{3} b^{3} + a^{2} b^{4}
