Factor the following. Check using FOIL then
solve for x:
x^2 + 3x + 2 = 0

x = -2 and -1

Step-by-step explanation:

x^2 + 3x + 2 = 0

Factorizing the given equation:

x^2 + 3x + 2 = 0

x^2 + 2x + x+ 2 = 0

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

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

x+2 = 0 and x+1 = 0

x = -2 and -1

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
