- Zero Product Property: if a × b = 0, then either a or b = 0 or both a and b = 0.
(Make sure to set f(x) to zero)
So for this equation, I will be factoring by grouping. Firstly, what two terms have a product of -5x^2 and a sum of 4x? That would be 5x and -x. Replace 4x with 5x - x:
Next, factor 5x^2 + 5x and -x - 1 separately. Make sure that they have the same quantity on the inside:
Now you can rewrite the equation as:
Now apply zero product property to the factors to solve for x:
<u>The x-intercepts are (1/5 ,0) and (-1,0).</u>
Answer:
<h2>B. 2x + y = 4</h2>Step-by-step explanation:
Having the system of equations in its simplest form
If
then the system of equations has infinitely many solutions.
If
then the system of equations has no solution.
If
then the system of equations has one solution.
We have the equation
Convert to the standard form Ax + By = C<em>:</em>
<em /><em> add 2x to both sides</em>
