What process could you use to determine the zeros, x-intercepts, or solutions of a polynomial y=9x^2+12x+4

Step-by-step explanation:

Y=9x²+12x+4

Y=9(x²+(12/9)x+4/9)

Y=9(x²+(4/3)x+4/9)

Y=9(x²+2(2/3)x+4/9)

Y=9(x²+2(2/3)x+4/9)

Y=9(x+2/3)²

Y = 0 : x+2/3 = 0

x = -2/3 is the solution of a polynomial

b

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
