Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q. 3 + x - 3x2 = 9
Triss [41]
To <span>transform the quadratic equation into the equation form (x + p)2 = q we shall proceed as follows:
3+x-3x^2=9
putting like terms together we have:
-3x^2+x=6
dividing through by -3 we get:
x^2-x/3=-2
but
c=(b/2a)^2
c=(-1/6)^2=1/36
thus the expression will be:
x^2-x/3+1/36=-2+1/36
1/36(6x-1)</span>²=-71/36

the answer is:
1/36(6x-1)²=-71/36

If f(x)=ax+b/x and f(1)=1 and f(2)=5, what is the value of A and B?
LUCKY_DIMON [66]

Answer:

\huge\boxed{a=9 ; b = -8}

Step-by-step explanation:

f(x) = \frac{ax+b}{x}

Putting x = 1

=> f(1) = \frac{a(1)+b}{1}

Given that f(1) = 1

=> 1 = a + b

=> a+b = 1  -------------------(1)

Now,

Putting x = 2

=> f(2) = \frac{a(2)+b}{2}

Given that f(2) = 5

=> 5 = \frac{2a+b}{2}

=> 2a+b = 5*2

=> 2a+b = 10  ----------------(2)

Subtracting (2) from (1)

a+b-(2a+b) = 1-10\\a+b-2a-b = -9\\a-2a = -9\\-a = -9\\a = 9

For b , Put a = 9 in equation (1)

9+b = 1\\Subtracting \ both \ sides \ by \ 9\\b = 1-9\\b = -8
