The zeros of the polynomial x2+16x−2 are
(a) -3, 4 (b) −32,43 (c) −43,32 (d) none of these
Polynomial : x2+16x−2
Comparing with the standard equation, we get
a = 1, b = 16 , c = -2
To find zero, equate it with 0
=> x2+16x−2=0
Multiply by 6
=> 6x2+x−12=0
=> 6x2+9x−8x−12=0
=> 3x(2x+3)−4(2x+3)=0
=> (2x+3)(3x−4)=0
2x+3=0 Or 3x−4=0
=> x = −32 or 43
so option b is correct
