Answer:

The answer to your question is: (x + 2)(3x - 1) = 0

x1 = -2

x2 = 1/3

Step-by-step explanation:

3x² + 5x − 2 = 0

Multiply 3 x -2 = -6

Find two numbers that added = +5 and multiply -6

These numbers are +6 and -1

Then:

3x² + 6x -1x − 2 = 0

Factorize 3x (x + 2) - 1(x + 2) = 0

Factorize again (x + 2)(3x - 1) = 0

Finally

x + 2 = 0 3x - 1 = 0

x = -2 x = 1/3

Find a24 in the sequence, -8, 12, 32, 52, ...

JulsSmile [24]

You can see that two consecutive terms always differ by 20.

In other words, you generate the next term in the sequence by adding 20 to the previous one.

This implies the following structure:

$\begin{array}{l}a_1=8\\a_2=a_1+20\\a_3=a_2+20=(a_1+20)+20 = a_1+2\cdot 20\\\ldots\\a_n = a_1+(n-1)\cdot 20\end{array}$

In particular, this implies

$a_{24} = a_1+23\cdot 20 = -8+460 = 452$

Answer:

12x^2

Step-by-step explanation:

All you need to do is combine like terms

since 9x^2 and 3x^2 are like terms with the same variable and same degree, they can be combined to get 12x^2
