Question

2x² + ax +3 =0 has equal roots find a​

Answer 1

Step-by-step explanation:

Given, the quadratic equation is,

2x²+ax+3=0

Here,

a=2 , b=a and c=3

we know that, when a quadratic equation has equal roots then,

b²-4ac =0

a²-4×2×3 =0

a²- 24 =0

a² =24

a =2√6

That's your answer. I hope it will help you.
