Question 464704: dhdghdgh be used solve any equation of the form ax2 +bx+c=0. a=3, b=6, and c=1.

You can put this solution on YOUR website! Evaluate the formula x=-b shorthand notation sign square b square -4ac divide by 2a for the given values of a,b, and c. Note that the symbol that looks like a plus sign with minus sign underneath is a shorthand notation to indicate that there are two solutions. One solution is obtained when the quantity after the shorthand notation sign/symbol is added, and another is obtained when subtracted. This formula can be used solve any equation of the form
ax2 +bx+c=0. a=3, b=6, and c=1.
-----------------
x = [-b +- sqrt(b^2-4ac)]/(2a)
---
x = [-6 +- sqrt(36-4*3*1)]/(2*3)
----
x = [-6 +- sqrt(24)]/6
---
x = [-6 +- 2sqrt(6)]/6
-----
x = -1+(1/3)sqrt(6) or -1-(1/3)sqrt(6)
