Answer:
Q1.
Add 3a(2a+3b) and 4b(3a+5b)
Therefore,
3a(2a+3b) + 4b(3a+5b)
= 6a²+9ab+12ab+20b²
= 6a²+21ab+20b² :Ans
Q2.
Add 2x(x-7y) and 3y(2x-y)
Therefore,
2x(x-7y)+3y(2x-y)
= 2x²-14xy+6xy-3y²
= 2x²-8xy-3y² :Ans
Q3.
Simplify 5m(x-7y) and 3y(2x-y)
Therefore,
5m(x-7y)
=5mx-35my :Ans
Therefore,
3y(2x-y)
= 6xy-3y² :Ans
