Answer:
Step-by-step explanation:
11) The degree of 5 is = 1
12)The zero of linear polynomial 2x + 3 is = - 3/2 and also -1 1/2
13)The product of the zeroes of the polinomial 3x^3 +- 5x ^2 - 10x + 15 is=-d/a= -15/3= -5
14) The value of 'a' is = 1
(1)^3 - 3 (1)^2 + 1 + 1 = 1 - 3 + 1 + 1 = 3 - 3 = 0
So,the value 'a' is = 1
15) Given, alpha = 5, beta = 2, gamma = -3
alpha × beta × gamma / alpha + beta + gamma
= 5×2×(-3) / 5+2-3 = -30 / 4 = -7.5
16) f (x) = 4x ^2 - 6x - k x -3 = 0 , x = 3
f (3) = 4 (3)^2 - 6 (3) - k =0, 36 - 18 - k =0, 18 - k =0, k = 18
17) Two zeroes of the polynomial x^3 + x ^2 - 9x - 9 are -3 and 3.
It's third zero is = -1
f (x ) = x^3 + x ^2 - 9x - 9
f (-1) = (-1)^3 + (-1)^2 - 9 (-1) - 9
= -1 + (1) + 9 - 9
= 0
So, the third zero is = -1.
18) The number of terms in a polynomial of degree 'n' is = n.
19) Coefficient of the monomial (√3x)^2 is = 3.
