For exercises 1–6, factor the expanded form of these quadratic expressions. pay particular attention to the negative and
positive signs.
1. 3x^2 − 2x − 8
2. 3x^2 + 10x − 8
3. 3x^2 + x − 14 [notice that there is a 1 as a coefficient in this one.]
4. 2x^2 − 21x − 36 [this might be a challenge. if it takes too long, try the next one.]
5. −2x^2 + 3x + 9 [this one has a negative on the leading coefficient.]
6. + 6
4 + 9
16 [we need to try one with fractions, too.]
for exercises 7–10, use the structure of these expressions to factor completely.
7. 100x^2 − 20x −63
8. y^4 + 2y^2 − 3
9. 9x^2 − 3x − 12
10. + − 6

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will
