●Combine multiplied terms into a single fraction

/2(−1)/2 (+2)=4

(−1)/2/2 (+2)=4

●Distribute

²−/2/2 (+2)=4

●Combine multiplied terms into a single fraction

(²−)(+2)/2/2 = 4

●Again Distribute

(+2)²−(+2)/2/2=4

³+2²−1²−2/2/2=4

●Multiply

³+ ²-2/2/2 = 4

●Multiply all terms by the same value to eliminate fraction denominators

2(³+²−2/2/2)=2⋅4

³ + ² - 2/2 = 8

●Multiply all terms by the same value to eliminate fraction denominators

2(³+²−2/2)=2⋅8

●Simplify

●Cancel multiplied terms that are in the denominator

●Multiply the numbers

³+²−2=16
