Which expression represents the fourth term in the binomial expansion of (e + 2f)10?
yan [13]

The fourth term of the binomial expansion (e+2f)^{10} can be calculated using the formula for (i+1)-th term of the binomial expansion:

T_{i+1}=C_{10}^i\cdot e^{10-i}\cdot (2f)^i.

In order to find term T_4, determine that

i+1=4\Rightarrow i=3.

Now

T_4=C_{10}^3\cdot e^{10-3}\cdot (2f)^3=C_{10}^3\cdot e^7\cdot (2f)^3.

Answer: correct choice is A

Find the values of a and b such that x2 - 2x + 2 = (x -a) + b LOADS OF POINTS ON THE LINE!!!
Hitman42 [59]

Answer:

Step-by-step explanation:

Factorize using square root method.

x² - 2x + 2 = (x-a)² + b

x² -2x + 1 + 1 = (x-a)²+b

(x² - 2*x*1 + 1²) + 1 = (x -a)²+ b       {Compare with a²- 2ab+b² which is (a - b)²}

(x - 1)² + 1 = (x - a)² + b

a = 1 and b = 1
