Question

(i) (a-b)' = a-bº-.......
(ii). Zero of the polynomial q(x) = bx+c is
(iii) Degree of polynomial p(x) = 4x +3x²+2x+7 is​

Answer 1

Answer:

(ii) x=-c/b

(III) 2

Step-by-step explanation:

(ii)

let q(x) =0

if q(x) = bx+c

then, bx+c = 0

bx=-c

x= -c/b

hence, zero of polynomial is (-c/b )

(iii) by arranging

it becomes

3x2 + 6x + 7

so the degree of polynomial is 2
