Examples Of Algebraic Formulas
Can you solve these quadratic formulas?……so i can revise!?
i need to check a few of my examples and answers so i can revise properly!
oh and for the squared symbol ive just put (2) and the X is algebraic
Thanks!
1. 3X(2)+X-5=0
2. 2X(2)+4X+1=0
3. X(2)-X-7=0
4. 3X(2)+X-1=0
5. 3X(2)+7X+3=0
6. 2X(2)+11X+1=0
7. 2X(2)+5X+1=0
8. X(2)+2X-9=0
9. X(2)+2X-6=0
Thanks again!
if possible please solve in stages e.g.
X(2)+7X+12=0
(X+3)(X+4)=0
X+3=0 OR X+4=0
X=-3 X=-4
The quadratic formula is the roots are equal to -b +/- the square root of b^2 – 4(a)(c) all over 2 a.
So b=any number that is x
a is any number ^2
c is any number that is just a plain number.
You can go to this site and type these in on your own!
