You must know that : (a-b) ^2 = a^2 - 2ab + b^2 so let a=x and b=2, applying above formula you'll get f(x) = x^2 - 4x +4 + 4 =x^2 - 4x +8 Hope you got it ;-) Revert back if you still face any trouble.

Geometric mean <br> Pls help thank u

quester [9]

Answer:

Step-by-step explanation:

1). Geometric mean of a and b = $\sqrt{a\times b}$

Therefore, geometric mean of 2 and 50 = $\sqrt{2\times 50}$

= 10

2). By geometric mean theorem,

$\frac{JM}{KM}=\frac{KM}{ML}$

$\frac{6}{e}=\frac{e}{24}$

e² = 6 × 24

e = √144

e = 12

Similarly, $\frac{JL}{KJ}=\frac{KJ}{JM}$

$\frac{6+24}{d}=\frac{d}{6}$

d² = 6 × 30

d = √180

d = 6√5

And $\frac{JL}{KL}=\frac{KL}{ML}$

$\frac{6+24}{c}=\frac{c}{24}$

c² = 30 × 24

c = √720

c = 12√5
