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

Find the smallest value of $x$ such that $x^2 + 10x + 25 = 8$.
Mashutka [201]

Answer:

-5 -√8  or ≈ -7.83

Step-by-step explanation:

<u>Solving the quadratic equation, to find its roots:</u>

  • x^2 + 10x + 25 = 8           ⇒ The left side is perfect square
  • (x+5)^2=8                         ⇒ Getting square root of both sides
  • x+5 = ± √8                       ⇒ There are 2 roots
  • x = - 5 ± √8

<u>The smallest root is:</u>

  • x= -5 - √8 ≈ -7.83
