Generate the first three terms of the following sequence 4n² - 2n + 3

Jet001 [13]

Answer:

=15

=33

Step-by-step explanation:

$n = 1 \\ 4 {n}^{2} - 2n + 3 \\ 4 \times 1 \times 1 - 2 \times 1 + 3 \\ 4 - 2 + 3 \\ 2 + 3 \\ = 5$

$n = 2 \\ 4 {n}^{2} - 2n + 3 \\ 4 \times 2 \times 2 - 2 \times 2 + 3 \\ 16 - 4 + 3 \\ 12 + 3 \\ = 15$

$n = 3 \\ 4 {n}^{2} - 2n + 3 \\ 4 \times 3 \times 3 - 2 \times 3 + 3 \\ 36 - 6 + 3 \\36 - 3 \\ = 33$

select whether the equation has a solution or not, square root x-2- square root 2x= square root x+2 (a. roots b. no roots)

Agata [3.3K]

The equation is $\sqrt{x-2 \\ \\$ - $\sqrt{2x}$ = $\sqrt{x +2}$

Solution

Take square on both sides, we get

3x - 2 $\sqrt{x-2}$ $\sqrt2{x}$ -2 = x +2

Subtract 3x - 2 from both sides, we get

-2 $\sqrt{x-2} \sqrt{2x} = -2x + 4$

Again, square on both sides in order to get rid of the square root from the above equation, we get

$8x^{2}-16x = 4x^{2} -16x +16$

Now we have to simplify it,

$4x^{2} -16 = 0$

Now we have to solve this quadratic equation, in order to get the solution.

We get x = 2 and x = -2, When we verifying solution in the original given equation, the solution does not satisfy the equation.

Reason: We get negative number in the square root.

Therefore, it has no Roots.

<em>Answer: b) No roots</em>
