having all the necessary or appropriate parts:
1. It's useful to divide out the GCF first because it makes factoring easier because the coefficients are smaller requiring less steps. 2. First, identify a,b, and c in the trinomial ax^2+bx+c. Then, write down all factor pairs of c Then, identify which factor pair from the previous step sums up to b. Then, Substitute factor pairs into two binomials 3. Key features are the y-intercept the zeros and the end behavior. to graph these put a pont on the intercepts and draw a line through them that matches the end behavior. 4. A binomial that is the difference of perfect squares is in the form of a^2-b^2 And its factor form is a^2 - b^2=(a-b)(a+b)5. Factoring by grouping often works well with four-term polynomials but the last step of factoring the common binomial only works when both terms contain the exact same binomial.

Answer:
C. -6 and -9
Step-by-step explanation:
For the polynomial to be zero, one or more of the factors must be zero. For the factors to be zero, we require ...
x +6 = 0
x = -6 . . . . . . subtract 6 from both sides of the equation
and likewise, ...
x +9 = 0
x = -9 . . . . . . subtract 9 from both sides of the equation
x = -6 or -9 will make the polynomial zero.
Answer:
D. (2x - 5)(2x - 5)
Step-by-step explanation:
4 is a perfect square, with its two identical factors being 2. The number 25 is also a perfect square, with its two identical factors being 5. This leaves us with the answer choices:
C. (2x + 5)(2x + 5)
OR
D. (2x - 5)(2x - 5)
However, when you solve answer "C," the result is:
![4x^2+20x +25](https://tex.z-dn.net/?f=4x%5E2%2B20x%20%2B25)
But we need the middle term to be -20x, so answer "D," is correct since it has -5 instead of positive 5.
