Factorise the following expressions.( i ) p^(2)+6p+8( ii) q^(2)-10q+21 (iii) p^(2)+6p-16

Factorise the following expressions. (i) p^2 + 6p +8 (ii) q^2-10q+21 (iii) p^2+6p-16

(i) 2P^(2)+9P+9 = 0 (ii) 15Q^(2) + 16Q + 4 = 0

Factorise: p ^(2) +6p -16

I. p^(2) - 8p+15 = 0 II. q^(2) - 5q =- 6

Add : 6p^(2)q - 5pq^(2) -3pq, 8pq^(2)+2p^(2)q -2pq

Add : 6p^(2)q - 5pq^(2) -3pq, 8pq^(2)+2p^(2)q -2pq

I. p^(2)+5p+6 = 0 II. q^(2) + 3q + 2 = 0

Factorize each of the following quadratic polynomials by using the method of completing the square: (1) p^2+6p+8 (2) q^2-10 q+21 (3) p^2+6p-16
