- 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:
This does not make sense.
Step-by-step explanation:
Just because you are a musician does not mean you play the guitar.
You can play the piano and a trumpet, but not be able to play a guitar!
6s as 6 goes into 24, 12 and 18
Answer:
see below
Step-by-step explanation:
6+9x^2
Rewriting in decreasing powers of x
9x^2 +0x + 6
ax^2+bx+c
a = 9
b =0
c = 6
This is an isosceles triangle. The angles at the base are congruent (they have the same measures).
Look at the picture.
We know: The sum of the measures of angles in a triangle is equal 180°.
Therefore we have the equation:
<em>combine like terms</em>

<em>subtract 5 from both sides</em>
<em>divide both sides by 7</em>
