Find the disciminant and the number of real roots for this equation x^2+3x+8=0

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
