2. Solve the quadratic equation by completing the square.

Mathematics

Paraphin [41]2 years ago

The roots of the quadratic equation are:

x = 0.74 - 0.6614i

x = 0.74 + 0.6614i

The given equation is:

2x² + 2 = 3x

Rearrange the equation

2x² -3x = -2

Divide through by 2

x² - (3/2)x = -1

x² - (3/2)x + (3/4)² = -1 + (3/4)²

(x - 3/4)² = -7/16

Square root both sides

x - 3/4 = √(-7/16)

x = 3/4 ± √(-7) / 4

x = 0.75 ± i√(7) / 4

x = 0.74 ± 0.6614i

Therefore, the roots of the quadratic equation are:

x = 0.74 - 0.6614i

x = 0.74 + 0.6614i

Please help me , I need help!!!
GaryK [48]

Answer:

An odd number times an even number is always even

e.g 2 × 3 = 6

4 × 5 = 20

adding 1 to an even number makes it odd

6 + 1 = 7

20 + 1 = 21

hope this helps...

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!<br><br> Factor.<br><br> 11x^2 + 35x + 6
fredd [130]

Hey there!!

Given equation :

11x² + 35x + 6

Now let's write 35x as 33x and 2x

Then the equation would become :

... 11x² + 33x + 2x + 6

... Now, let's take the common terms 11x² + 33x and 2x + 6

It would become :

... 11x ( x + 3 ) + 2 ( x + 3 )

... Now, we will write this as :

... ( 11x + 2 ) ( x + 3 )

Hence, this is as the answer...

Hope my answer helps!!

The answer is y=(1/2)x -5

You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m

Then work out like a one step equation
