Q96Multiple choice
Factorise the expressions and divide them as directed:
- (i)(x2 – 22x + 117) ÷ (x – 13)
- (ii)(x3 + x2 – 132x) ÷ x (x – 11)
- (iii)(2x3 – 12x2 + 16x) ÷ (x – 2) (x – 4)
- (iv)(9x2 – 4) ÷ (3x + 2) (v) (3x2 – 48) ÷ (x – 4) (vi) (x4 – 16) ÷ x3 + 2x2 + 4x + 8 (vii) (3x4 – 1875) ÷ (3x2 – 75)
Show answer
(i) (x2 – 22x + 117) ÷ (x – 13)
(ii) (x3 + x2 – 132x) ÷ x (x – 11)
(iii) (2x3 – 12x2 + 16x) ÷ (x – 2) (x – 4)
(iv) (9x2 – 4) ÷ (3x + 2) (v) (3x2 – 48) ÷ (x – 4) (vi) (x4 – 16) ÷ x3 + 2x2 + 4x + 8 (vii) (3x4 – 1875) ÷ (3x2 – 75)
