Answer 3

that website should help u alot

Answer 4

First, notice there is no common factor to be pulled out.

Answer 5

ok

Answer 6

@britbrat4290 How exactly did your answer explain to @romanortiz65 how to answer this question?

Answer 7

Now we multiply ac, 8 * (-35) = -280

Answer 8

mathstudent55 can u help me in another problem it tells me factor in a polynomial in descending order

Answer 9

i did i put the link to it ... lol

Answer 10

Now we need two factors of -280 that add to 6.
280 = 2^3 * 5 * 7 = 20 * 14
So use 20 and -14

Answer 11

ok

Answer 12

factor the trinomial x2+7x+10 write each factor as a polynomial in descending order can u help me in this one

Answer 13

can you help in this problem please

Answer 14

Now we break up the middle term using those two numbers:

\(8x^2 - 14x + 20x - 35 \)

Factor by parts:

\( 2x(4x - 7) + 5(4x - 7) \)

Now factor out the common focator of 4x - 7:

\((4x - 7)(2x + 5) \)

Answer 15

Now let's factor this triniomial:
\(x^2+7x+10 \)

This problem is simpler because a = 1. In other words you have only x^2, not a number times x^2.

All you need to do is find 2 numbers that multiply to 10 and add to 7.

Answer 16

2,10

Answer 17

i mean 2,5

Answer 18

so is it (x+5) (x+2)??

Answer 19

Right.
Since this is the easier case, all you do is

\((x + 2)(x + 5) \)

Answer 20

Correct.
