Solve (a*b*a*b)+(a*a*b*b)

$$( a \times b \times a \times b ) + ( a \times a \times b \times b )$$

Evaluate

$$2\left(ab\right)^{2}$$

Solution Steps

Multiply a and a to get a^{2}.

$$a^{2}bb+aabb$$

Multiply b and b to get b^{2}.

$$a^{2}b^{2}+aabb$$

Multiply a and a to get a^{2}.

$$a^{2}b^{2}+a^{2}bb$$

Multiply b and b to get b^{2}.

$$a^{2}b^{2}+a^{2}b^{2}$$

Combine a^{2}b^{2} and a^{2}b^{2} to get 2a^{2}b^{2}.

$$2a^{2}b^{2}$$

Differentiate w.r.t. a

$$4ab^{2}$$
