Question

Maths chapter-polynomials

Answer 1

Answer:

(i) p(x) = q(x) ×g(x) + r(x)

(ii) zeros are -3,4

sum zeros =-3+4 = 1

product of zeros = -3×4 = -12

X2 - ( sum of zeros) x + product of zeros

x^2-x-12

(iii)x^2-5x-6

x=6

(6)^2-5(6)-6

36-30-6

36-36 = 0

(iv) x^2-5x+4

x=3

(3)^2-5(3)+4

9-15+4

13-15 =-2

so -2 should be added to the poly.

(v) zeros are ;ß ,-ß

or

alpha ,-alpha
