Question 1 of 10
1. Question
If p(x) = 3x^{2}+4x+6 , p(3) is
Correct
Explanation:
p(x) = 3x^{2}+4x+6
p(3) = 3 X 3^{2} + 4 X 3 + 6
= 3 X 9 + 12 + 6
= 27 + 12 + 6 = 45
Incorrect
Explanation:
p(x) = 3x^{2}+4x+6
p(3) = 3 X 3^{2} + 4 X 3 + 6
= 3 X 9 + 12 + 6
= 27 + 12 + 6 = 45

Question 7 of 10
7. Question
If p(y) = 4y^{3} + 5x^{2} + 6 , then p(2) is
Correct
Explanation:
p(y) = 4y^{3} + 5x^{2} + 6
p(2) = 4 X 2^{3} + 5 X 2^{2} + 6
= 4 X 8 + 5 X 4 + 6
= 32 + 20 + 6 = 58
Incorrect
Explanation:
p(y) = 4y^{3} + 5x^{2} + 6
p(2) = 4 X 2^{3} + 5 X 2^{2} + 6
= 4 X 8 + 5 X 4 + 6
= 32 + 20 + 6 = 58

Question 8 of 10
8. Question
If q(x) = 6x^{2}+ 7x+7 , then q(3) is
Correct
Explanation:
q(x) = 6x^{2 }+ 7x + 7
q(3) = 6 X 3^{2} + 7 X 3 + 7
= 6 X 9 + 7 X 3 + 7
= 54 + 21 + 7 = 82
Incorrect
Explanation:
q(x) = 6x^{2 }+ 7x + 7
q(3) = 6 X 3^{2} + 7 X 3 + 7
= 6 X 9 + 7 X 3 + 7
= 54 + 21 + 7 = 82

Question 9 of 10
9. Question
The zero of the polynomial p(x) = 3x – 4 is
Correct
Explanation: For a polynomial p(x), if p(a) = 0 ,then we say a is the zero of the polynomial.

3x4 = 0
3x =4
x = 4/3Incorrect
Explanation: For a polynomial p(x), if p(a) = 0 ,then we say a is the zero of the polynomial.
p(x) = 0
3x4 = 0
3x =4
x = 4/3

10. Question
The zero of the polynomial g(x) = 3x + 15 is
Correct
Explanation: For a polynomial g(x), if g(a) = 0 ,then we say a is the zero of the polynomial.
g(x) = 0
3x+15 = 0
3x = 15
x = 5
Incorrect
Explanation: For a polynomial g(x), if g(a) = 0 ,then we say a is the zero of the polynomial.
g(x) = 0
3x+15 = 0
3x = 15
x = 5
