Use geometric model to factor x2+3x+2

-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

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
