Answer:

(vi) Option b

(vii) Option c

(viii) Option c

(ix) Option d

(x) Option a

Explanation:

(vi) (a - 7)(a + 2) = a² + 2a - 7a - (7)(2) = a² - 5a - 14

Option b is the correct answer.

(vii) -2 will be sum when the greater number is negative and the smaller number is positive.

-11 + 9 = -2 and (-11) x (9) = -99

Hence, option c is the correct answer.

(viii) x² + (a +b)x + ab

= x² + ax + bx + ab

= x (x + a) + b (x + a)

= (x + a)(x + b)

Option c is the correct answer.

(ix) x² - 10x + 21

= x² - 7x - 3x + 21

= x (x - 7) -3 (x - 7)

= (x - 7)(x - 3)

Option d is the correct answer.

(x) p² + 6p - 16

= p² + 8p - 2p - 16

= p (p + 8) -2 (p + 8)

= (p + 8)(p - 2)

Option a is the correct answer.
