A rectangle has an area of x2 + 7x – 18. Factor to determine algebraic expressions for the
possible lengths of the sides.

Step-by-step explanation: Let's see if we can factor

x

2

−

x

−

72

. What two numbers sum up to

−

1

and have a product of

−

72

?

After some trial and error, we arrive at

−

9

and

8

. Thus, we now have

(

x

−

9

)

(

x

+

8

)

Where these can represent the sides of the rectangles.

Hope this helps!

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

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

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
