Answer 1

︎39y³(50y²-98) ÷ 26y²(5y+7)

let's factorise the LHS

39y³(50y²-98)

39y³(5×5×2×y×y - 2×7×7)

3×13×y×y×y{2(25y²-49)}

let's factorise the RHS

26y²(5y+7)

2×13×y×y(5y+7)

3×13×y×y×y(2×5×5×y×y-7×7)

2×13×y×y(5y+7)

3×y(2×5×y-1×7)

3y(10y-7)

__________________________________

︎(10a-35)÷(2a-7)

let's factorise the LHS

︎(10a-35)

2×5×a - 5×7

let's factorise the RHS

(2a-7)

2×a-7

2×5×a - 5×7

2×a-7

5-5
