What is 2x^2+9x-18 in vertex form?
atroni [7]

Complete the square:

2<em>x</em>² + 9<em>x</em> - 18

2(<em>x</em>² + 9/2 <em>x</em>) - 18

2(<em>x</em>² + 9/2 <em>x</em> + 81/16 - 81/16) - 18

2(<em>x</em>² + 2 (9/4) <em>x</em> + (9/4)²) - 81/8 - 18

2(<em>x</em> + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

<em>ax</em>² + <em>bx</em> + <em>c</em>

into its vertex form

<em>a</em> (<em>x</em> - <em>h</em>)² + <em>k</em>

where (<em>h</em>, <em>k</em>) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

<em>a</em> (<em>x</em>² - 2<em>xh</em> + <em>h</em>²) + <em>k</em>

<em>ax</em>² - 2<em>ahx</em> + <em>ah</em>² + <em>k</em>

For the two forms to be equivalent, we must have

-2<em>ah</em> = <em>b</em>

<em>ah</em>² + <em>k</em> = <em>c</em>

which means

<em>h</em> = -<em>b</em>/(2<em>a</em>)

<em>k</em> = <em>c</em> - <em>ah</em>² = <em>c</em> - <em>b</em>²/(4<em>a</em>)

In this case, <em>a</em> = 2, <em>b</em> = 9, and <em>c</em> = -18, so

<em>h</em> = -9/(2 • 2) = -9/4

<em>k</em> = 18 - 9²/(4 • 2) = -225/8

Could you plz help me with this question?​
Flauer [41]

Answer:

(a) t_n = 3n - 9

(b) t_16 = 39

Step-by-step explanation:

(a)

-3 - (-6) = -3 + 6 = 3

The common difference is 3.

t_1 = -6

t_2 = -6 + 3

t_3 = -6 + 3 + 3

t_4 = -6 + 3 + 3 + 3

t_n = -6 + 3(n - 1)

t_n = -6 + 3n - 3

t_n = -9 + 3n

t_n = 3n - 9

The formula is: t_n = 3n - 9

(b) t_16 = 3(16) - 9 = 48 - 9 = 39
