: Please help, I am having difficulty trying to figure Quadratic Equations. On page #575 of Begining Algebra Questions 2, 4, 6 and 14 are the ones I need help with. I need to write them in standard form and determine the values of a,b, and c. Your help is very appreciated. Thanks!! =)
#2. x^2+6x-5=0
#4. 4x^2+20x=0
#6. 3x^2+10x+8= -17x-2
#14. x^2+3x-40=0

You can put this solution on YOUR website!
IF YOU JUST WANT THE VALUES OF (A)X^2+(B)X+(C) THEN YOU ALREADY HAVE THEM.
2) X^2+6X-5=0 HERE YOU HAVE A=1, B=6 & C=-5
IF YOU NEED TO FIND THE TWO TERMS OR X THEN YOU NEED TO USE IN THIS CASE THE QUADRATIC EQUATION:
X=(-6+-SQRT[6^6-4*1*-5])/2*1
X=(-6+-SQRT[36+20])/2
X=(-6+-SQRT56)/2
X=(-6+-7.48)/2
X=(-6+7.48)/2
X=1.48/2
X=.74 ANSWER
X=(-6-7.48)/2
X=-13.48/2
X=--6.74 ANSWER.
