Question

(iii) - 6a+b(a+ + b4 - 3a+b) solution​

Answer 1

Answer:

there are total 2 terms in this whole expression, so first we will multiply the first term with the second term. Then, the answer will automatically come. Here's the step by step explanation!

Step-by-step explanation:

-6a+b(a+b4-3a+b)

⇒ (-6a²-24ab-6ab) + (ab+4b²-3ab+b²)

 (first term of the first term which is -6a multiplied with the second term which is a+b4-3a+b results this  (-6a²-24ab-6ab) then we do the same with the second term of the first term which is +b multiplied by the second term (a+b4-3a+b) which results to (ab+4b²-3ab+b²)

⇒now we open the brackets

⇒ -6a²-24ab-6ab+ab+4b²-3ab+b² (then we do arrangement)

⇒-24ab-6ab-3ab+ab+4b²+b²-6a²

⇒-32ab+5b²-6a²  (ans)
