Question

solve the following quadratic equation for X and give answer correct to three significant figures 2xsquare-4x-3=0

Answer 1

Answer:

Step-by-step explanation:

formula for that = -b+$\sqrt{b2-4ac}$ / 2a

      2x2-4x-3=0

    a=2,b=-4,c=-3

     -(-4)+$\sqrt{(-4)^{2}-4(2)(-3) }$ /2(2)

  ==  4+$\sqrt{16+24}$ /4

 ==  4+$\sqrt{40}$ /4

 ==  

Answer 2

$2x { }^{2} - 4x - 3 = 0$
