Let a= x^2 +4. Rewrite the following equation in terms of a and set it equal to zero.
swat32

Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as (x^2+4)^2+32=12x^2+48.

We can simplify the expression using the term a by replacing x^2 + 4 with a.

(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0                 a=4

a-8=0                   a=8

? ÷ 10,000 = 55,516 - ? = 5.5516

55,516,000,000 ÷ 10,000 = ? - ? = 5551600
