Use a geometric model to factor x2 + 3x + 2 by following
these steps

-1 and -2

Step-by-step explanation:

x ²+3x+2 = 0

We can solve the expression by first factorizing.

Factorizing by splitting the middle term

we look for 2 numbers that when multiplied will be +2 and when added it will be +3

+2 and +1 = +3 and 2 ( these is correct because it is the same as the question asked)

-2 and -1 = -3 and 2

x²+2x+x+2 = 0

x(x+2)+1(x+2) =0

(x+1)(x+2)= 0

x+1 = 0   x+2=0

x= -1,     x= -2

x = -1 and -2

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
