Use geometric model to factor x2+3x+2

-1 and - 2

Step-by-step explanation:x ²+3x+2 = 0

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

-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
