Exercise 14.3 (Part)

(e) 5pq(p2–q2)÷2p(p+q)

Answer: 5pq(p2–q2)÷2p(p+q)

Using (a+b)(a–b)=a2–b2; the equation can be written as follows:

=5pq(p+q)(p–q)÷2p(p+q)

=5q(p–q)÷2

(f) 12xy(9x2–16y2)÷4xy(3x+4y)

Answer: 12xy(9x2–16y2)÷4xy(3x+4y)

This can be solved as previous question;

=3(3x+4y)(3x–4y)÷(3x+4y)

=3(3x–4y)

(g) 39y3(50y2–98)÷26y2(5y+7)

Answer: 39y3(50y2–98)÷26y2(5y+7)

=2×39y3(25y2–49)÷26y2(5y+7)

=3y(25y2–49)÷(5y+7)

=3y(5y+7)(5y–7)÷(5y+7)

=3y(5y–7)

Thank you.
