Answer:
Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
The top 2 boxes, the first one because they are parallel which means lines that never meet or intersect, and the second box because it doesn’t have another line, which means it won’t intersect.
Different collections in total? Or like pairs of 2 how many?
To simplify a fraction, you want to divide both the numerator and the denominator by a number they have in common that is not 1.
For example;
Both of these numbers are divisible by 4, so divide both by 4.
4 / 4 = 1
8 / 4 = 2
We are now left with our simplified fraction:
I hope this helps!
