Factor x3-2x2-9x+18 completely if(x+3) is a factor
Charra [1.4K]

Factor x^3 -2x^2-9x+18

= x^2(x - 2) - 9(x - 2)

= (x^2 - 9)(x -2)

= (x + 3 )(x - 3)(x - 2)

So (x+3) is a factor

Integrate sin²2x cos²2x dx
DochEvi [55]
\sin^2x=\dfrac{1-\cos2x}2
\cos^2x=\dfrac{1+\cos2x}2

From the identities above, you have

\sin^22x\cos^22x=\dfrac{(1-\cos4x)(1+\cos4x)}4=\dfrac{1-\cos^24x}4

Applying once more, you have

\dfrac{1-\cos^24x}4=\dfrac{1-\dfrac{1+\cos8x}2}4=\dfrac{1-\cos8x}8

So,

\displaystyle\int\sin^22x\cos^22x\,\mathrm dx=\frac18\int(1-\cos8x)\,\mathrm dx=\frac x8-\frac1{64}\sin8x+C

What is the inverse of f(x)=−3x+5?
kotykmax [81]

Answer:

f-¹(x) = (4- x)/ 3

Step-by-step explanation:

inverse of a function is nothing but the value of x in terms of f(x)

like

if we write f(x) as y we'd get

y = - 3x + 5

so, ill express x in terms of y:-

y= -3x + 4

  • adding 3x on both sides of the equation

y + 3x = -3x + 3x + 4

  • subtracting y on both sides

y - y + 3x = 4 - y

3x = 4 - y

  • dividing the whole equation by 3

x = (4 - y)/ 3

soo, the inverse of the function is x = (4- y)/ 3

mostly we write the inverse in terms of x, hey! don't get confused, when i say this, I simply mean that we're gonna replace y with x and x with f-¹(x).

therefore,

f-¹(x) = (4- x)/ 3
