Answer 1

Answer:

ax+b=0

ax=-b

a=-b/a

So - b/a is the zero of the polynomial

x+3=0

x=-3

x-4=0

x=4

So - 3,4 are the zeros of polynomial

Answer 2

Answer:

(i). is zero ; (ii) are zeros

Step-by-step explanation:

(i) p(x) = ax + b at x = $-\frac{b}{a}$

p( $-\frac{b}{a}$ ) = $\frac{a}{1}$ × ( $-\frac{b}{a}$ ) + b = - b + b = 0 ⇒ ( $-\frac{b}{a}$ ) is a zero of given polynomial.

(ii) p(x) = (x + 3)(x - 4) at x = 4 and x = - 3

p(4) = (x + 3)(4 - 4) = (x + 3) × 0 = 0 ⇒ 4 is a zero of given polynomial.

p(- 3) = ( - 3 + 3)(x - 4) = 0 × (x - 4) = 0 ⇒ (- 3) is an another zero of p(x) = (x + 3)(x - 4)
