Question

Zeroes of the polynomial x(x+7) is / are
a) -7 b) 7 c) 0 d) none of these

Answer 1

IT IS GIVEN THAT X(X+7) =0

SENDING THE COMMON VARIABLE 'X' ON OTHER SIDE. IT MEANS THAT X*0 = 0. THEREFORE THE REMAINING EQUATION IS

        ( X + 7 ) = 0

          X = - 7

B) -7 IS THE CORRECT OPTION
