Question

x2+x+2=0 by using the quadratic formula

Answer 1

Hi ,

Compare x² + x + 2 = 0 with ax² + bx + c = 0

we get ,

a = 1 , b = 1 , c = 2

discreaminant ( D ) = b² - 4ac

D = 1² - 4 × 1 × 2

D = 1 - 8

D = -7

√D = ± √-7

√D = ± i√7

Now , according to Sridharacharya formula:

x = [ -b ± √D ]/2a

x = [ -1 ± i√7 ]/ 2

I hope this helps you.
