Answer:
A. 144 in
Step-by-step explanation:
Squares have congruent sides.
One side is 12 inches, so all of the other sides are 12 inches.
To find the area of a square, multiply width by height. The width is 12, and the height is also 12
12 * 12 = 144
144 in ^2
A + b = 0
ab = √(5)
since b = -a, subst into other equation
ab = √5
a(-a) = √5
-a² = √5
a² = - √5
a =± (5)^(1/4)·i
so our two zeros are (5)^(1/4) · i and -(5)^(1/4) · i.
Our polynomial has equation
difference of squares: (x + y)(x - y) = x² - y² so
your polynomial is
y = x² + √(5)
y = x^2 + sqrt(5)
