A=x^2+4
(x^2+4)^2+32=12x^2+48
12x^2+48=12(x^2+4)
(x^2+4)^2+32=12(x^2+4)
a^2+32=12a
subtract 12a from both sides
a^2-12a+32=0
factor
(a-4)(a-8)=0
set each to zero
a-4=0
a=4
a-8=0
a=8
a=4 or 8
a=x^2+4

8=x^2+4 and
4=x^2+4
subtract 4
4=x^2
0=x^2
square root
+/-2=x
0=x
x=-2,0,2
ax^2+bx+c=0
coefficient of the a term is 1
constant=32

A = x² + 4
& (x² + 4) +32 = 12x² + 48. You can factorize the left side of this equation

So 12x² + 48 = 12(x² + 4)==> (x² + 4) +32 = 12(x² + 4)
Now replace (x² +4) by a ==> a +32 = 12a
transpose all on the left side: a+32 -12a = 0==> -11a + 32 = 0
If you are asked to calculate then -11a=-32 & a=32/11

Find the average rate of change of f(x)=2x^2-7x from x=2 to x=5
m_a_m_a [10]

Answer:

7

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [2, 5 ]

f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15

f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus

average rate of change = \frac{15-(-6)}{5-2} = \frac{21}{3} = 7
