More solving quadratic equations: the quadratic formula again, what we've all been waiting for. the quadratic formula is pretty
easy to remember, and will always work, even if the solutions to the quadratic equation aren't always real numbers (they can be imaginary - the square roots of negative numbers). so here it is: _______ x = -b ± √b2 - 4ac 2a
1 answer:
You don't have a question in there but I can tell you that the quadratic formula that is shown is not quite correct.
<span>x = -b ± √b2 - 4ac 2a
For one thing, the first 3 terms should ALL be divided by 2a
The square root symbol should be extended from b^2 through 4ac
The division symbol is missing.
So the quadratic formula SHOULD read:
x = [-b +- sq root (b^2 - 4ac) ] / 2a
Also I have attached a graphic of the quadratic formula.

Answer:
There's a picture pf ratio tables below if you would like to view that.
Step-by-step explanation:
Let me explain this table to you. So in the first part. 1 group has 5 apples in it. Second group has ten. If you look the pattern you can tell that the groups are always multiplied by 5. 1 x 5 equals to 5. 2 x 5 equals 10. 4 x 5 equals 20 and so on. at the very end it's 135 times 5 equals 160. So there ya go for the ratio tables. I really hope this helps you. (times 5 is the ratio)
