Factor 9y^2-12y+4

(3y-2)^2
(3y-2)(3y+2)
(3y-4)(y+1)

(3y-2)^2

Step-by-step explanation:

To factor the polynomial, find the binomials which multiply to make it. This can be done for any polynomial by finding numbers that multiply to a*c and add to b.

a*c=36             b=-12

36: 1, 2, 3, 4, 6. 6. 9, 12, 18, 36

Since -6*-6 = 36 and -6 + -6 = -12, split -12y in   to  .

Next, factor by grouping by finding GCF between pairs of terms:

(3y-2)^2 is the solution.

the 3rd option is right

step-by-step explanation:

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
