Answer:
Step-by-step explanation:
Here, following formula will be used
(a+b)²= a²+b²+2ab
question
5(3a + b)² +6 (3a +b) - 8
=> we will take out 3 as common number to make the term (3a+b) to fit formula requirement
=> 5x3 (a+b/3)²+6(3a+b)-8
=> 15(a²+b²/9+2xaxb/3)+18a+6b-8
here, we have expanded the formula
=> 15a²+15b²/9+15x2ab/3+18a+6b-8
=> 15a²+5b²/3+10ab+18a+6b-8
The answer is 351/22
Steps:
1. You turn the mixed numbers into improper fractions, your new numbers are 211/11 and 71/22
2. Since your least common multiple would be 22 you do 11 times 2 and 211 times 2. Now 211/11 becomes 422/22
3. You do 422/22 minus 71/22
4. Your answer is 351/22
