Question

If one of the zeros of 2x² + ax + 3 is 1, find the other zero and the value
of a​

Answer 1

Answer:-

• 2x² + ax + 3
• putting zero of the polynomial
• p(1)= 2(1)² + a(1) + 3
• evaluation gives a=-5
• now the other zero of the polynomial =
• 2x² + ax + 3 =
• 2x² + -5x + 3=0
• 2x² +-2x-3x + 3=0
• 2x (x-1) -3 (x-1)
• therefore (2x -3)(x-1)
• x=3/2 is the other zero

Answer 2

Answer:

2(1) ^2 + a ×1 +3 =0

2+a+3=0

5+a=0

a =-5

2x^2 -5x +3 =

2x^2 -2x-3x +3=0

2x(x-1) -3(x-1) =0

(2x-3) (x-1) =0

2x-3=0, x-1=0

2x=3 , x=1

x=3/2 , x=1 ans
