Which polynomial is factored completely? 121 x squared + 36 y squared
(4x + 4)(x + 1)
2 x (x squared minus 4)
3 x Superscript 4 Baseline minus 15 n cubed + 12 n squared

9514 1404 393

  a, d

Step-by-step explanation:

We assume you want factors that use real integers.

a) 121x² +36y² . . . . cannot be factored using real numbers

b) (4x +4)(x +1) = 4(x +1)²

c) x(x² -4) = x(x -2)(x +2)

d) x⁴ -15n³ +12n² . . . . cannot be factored*

* If the polynomial is n⁴ -15n³ +12n², then it factors as n²(n² -15n +12).

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

a - base

b - exponent
