Question

Solve 2x^2-5x+14=0 and state the number and types of roots. I dont understand how to either factor it or or to unsquare the 2x

Answer 1

actually you dont factor it...the question is to determine the roots so you use quadratic formula to find the discriminant

discriminant = b^2 - 4ac

25 - 4(2)(14)
25 - 112
=-87

x is imaginary...2 imaginary roots

Answer 2

Thank-you, i didnt even think about the quadratic equation
