Question 4(iii) Divide as directed 52pqr(p+q)(q+r)(r+p)÷104pq(q+r)(r+p)
52pqr(p+q)(q+r)(r+p)÷104pq(q+r)(r+p)=2×2×13×p×q×r×(p+q)×(q+r)×(r+p)2×2×2×13×p×q×(q+r)×(r+p)=12r(p+q)
Divide as directed.
(i)5(2x+1)(3x+5)÷(2x+1)
(ii)26xy(x+5)(y−4)÷13x(y−4)
(iii)52pqr(p+q)(q+r)(r+p)÷104pq(q+r)(r+p)
(iv)20(y+4)(y2+5y+3)÷5(y+4)
(v)x(x+1)(x+2)(x+3)÷x(x+1)
Question 5(a) Add :p ( p - q ), q (q - r ) and r (r - p ).
