Solve 4a^2-b^2,b^2

$$4 a ^ { 2 } - b ^ { 2 } , b ^ { 2 }$$

Least Common Multiple

$$b^{4}-4\left(ab\right)^{2}$$

Solution Steps

Factor the expressions that are not already factored.

$$4a^{2}-b^{2}=\left(2a+b\right)\left(2a-b\right)$$

Identify all the factors and their highest power in all expressions. Multiply the highest powers of these factors to get the least common multiple.

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

Expand the expression.

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

Evaluate

$$4a^{2}-b^{2},b^{2}$$
