Question

Please help me solving 7 questions of level 1

Answer 1

Q1 The number on times the line cuts the x axis, it is the total no. of zeroes.


Q2 A + B= -b/ a

= -1

AB = c/a

= 1

1/ A + 1/ B = A+ B/ AB

= -1/ 1 = -1


Q4 Sum of zeroes = -b/ a

= 5 ÷ 1/3 = 5 x 3 = 15

Product of zeroes = c/ a

= 3/2 ÷ 1/ 3 = 3/2 x 3/1 = 9/ 2



Q6 If x is the zero of the polynomial 3x + 4

then, 3x + 4 = 0

3x = -4

x = -4/ 3


Q7 There is no degree of a zero polynomial. So, the answer is not defined.
