Solve P_{1}(2)=128/3+30

$$P _ { 1 } ( 2 ) = \frac { 128 } { 3 } + 30$$

Evaluate

$$\frac{218}{3}\approx 72.666666667$$

Solution Steps

Convert 30 to fraction \frac{90}{3}.

$$\frac{128}{3}+\frac{90}{3}$$

Since \frac{128}{3} and \frac{90}{3} have the same denominator, add them by adding their numerators.

$$\frac{128+90}{3}$$

Add 128 and 90 to get 218.

$$\frac{218}{3}$$

Factor

$$\frac{2 \cdot 109}{3} = 72\frac{2}{3} = 72.66666666666667$$
