Solve 8-bb/10

$$8 - \frac { b b } { 10 }$$

Evaluate

$$-\frac{b^{2}}{10}+8$$

Short Solution Steps

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

$$8-\frac{b^{2}}{10}$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 8 times \frac{10}{10}.

$$\frac{8\times 10}{10}-\frac{b^{2}}{10}$$

Since \frac{8\times 10}{10} and \frac{b^{2}}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{8\times 10-b^{2}}{10}$$

Do the multiplications in 8\times 10-b^{2}.

$$\frac{80-b^{2}}{10}$$

Factor

$$\frac{80-b^{2}}{10}$$

Solution Steps

Factor out \frac{1}{10}. Polynomial 80-b^{2} is not factored since it does not have any rational roots.

$$\frac{80-bb}{10}$$
