Factorize the following using identities:
(i) 9a – 2552
(ii)48p? – 279
(iii) 36×2 + 60xv + 25y
(iv) (20-h)? -9c
(v) x2 + 412 – 4x) – 922
(vi) XV – yx
Factorize the following by using (x + a) (x + b) = r + (a + b)x+ ab
(i) x2 + 14x + 45
(ii) – 22x + 120
(iii) y2 + 5y – 36
(iv) 0 + 3a-88
(v) x² – 4x – 21
Divide as directed:
(i) 18a²bby bab?
(ii)72u h’ by (-8a+b)
(iii) (-4a + 120 – 16a) by 4a
(iv) (r? – 5x + 6) by (x – 3)
(v) (ar? – ayº) by (ax +ay)
(vi) (- + 8y + 12) by (3+6)
