Solve 4(c+a)(c-a)

$$4 ( c + a ) ( c - a )$$

Evaluate

$$4\left(c^{2}-a^{2}\right)$$

Solution Steps

Use the distributive property to multiply 4 by c+a.

$$\left(4c+4a\right)\left(c-a\right)$$

Apply the distributive property by multiplying each term of 4c+4a by each term of c-a.

$$4c^{2}-4ca+4ac-4a^{2}$$

Combine -4ca and 4ac to get 0.

$$4c^{2}-4a^{2}$$

Expand

$$4c^{2}-4a^{2}$$

Solution Steps

Use the distributive property to multiply 4 by c+a.

$$\left(4c+4a\right)\left(c-a\right)$$

Apply the distributive property by multiplying each term of 4c+4a by each term of c-a.

$$4c^{2}-4ca+4ac-4a^{2}$$

Combine -4ca and 4ac to get 0.

$$4c^{2}-4a^{2}$$
