Question

1.If x+1 is a factor of the polynomial p(x) = x^2-3ax +3ax+3a-7, find the value of a.

2.Find the quadratic polynomial the sum of whose zeroes is 0 and one of the zero is 5.

3.If 2 is a zero of the polynomial p(x)= x^2 + bx +12 and g(x) = x^2 - bx +q, find b and q​

Answer 1

Answer:

( 1 )  g(x) = x + 1 = 0

      = x = -1

p(x) = x^2-3ax+3ax+3a-7 = 0

     = 1+3a-3a+3a-7 = 0

     = 3a-6 = 0

     = 3a = 6

      a = 2
