for the equation: -2h² - 28h - 98 = 0 can be factored as follows: -2(h² + 14h + 49) = 0;
to solve, the expression in parenthesis must equal zero: (h² + 14h + 49) = 0. We are looking for values, which when added equal 14, and when multiplied equal 49.
(h + a)(h + b) = 0, where we want a+b = 14, and ab = 49. The answer is a = 7 and b = 7, so we have (h + 7)(h + 7) = 0, and h = -7,-7 [double root].

When do you divide polynomials?
In real life you will probably never divide polynomials, but you need to know how to solve homework and exam problems.
What application does zeros of a function can be used?
To solve all sorts of problems. Any equation can be written in the form: (some expression) = 0 Simply by putting everything to the left. It turns out that polynomials are especially easy to solve if you put them in that form - because then you can solve them simply by factoring them. In other cases, for other functions, it might be more of a convention to put them in that form.
How do you solve v squared plus 6v plus 8 equal 0?
In this case, the left part of the equation can easily be factored. If you are not familiar with factoring polynomials, use the quadratic formula.================================================v2 + 6v + 8 = 0(v + 4) (v + 2) = 0v = -4andv = -2
How do you solve a factoring polynomials problem if there is no greatest common factor?
If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised.
