Expert Solution

Answer to Problem 67E

  x=32,x=1

Explanation of Solution

Given information:

  2x2+x3=0

Formula used: -

  x=b±b24ac2a

  2x2+x3=0

Now applying quadratic formula:

  x=b±b24ac2a In equation 2x2+x3=0

Here a=2,b=1,c=3

  x=(1)±(1)24(2)(3)2(2)x=1±1+244x=1±254x=1±54

  x=154,x=1+54x=32,x=1
