Math never seems to end.

Numbers keep going and going. 

This means endless possibilities to how we solve math and mathematical problems. 

Math is all around us; without Math, our daily lives would be very different. 

The world depends on Math to advance in science and in technology; in other words, to make our lives easier.

I hope this answered your question.

We've all been there, my friend. Much love. <3

Brainliest answer is always appreciated!

Tran is solving the quadratic equation 2x2 – 4x – 3 = 0 by completing the square. His first four steps are shown in the table.
natulia [17]

The solution to the quadratic equation 2x² - 4x - 3 = 0 is x = 1 ± √2.5

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Solving the polynomial using completing the square:

2x² - 4x - 3 = 0

First divide through by 2:

x² - 2x - 3/2 = 0

add 3/2 to both sides:

x² - 2x - 3/2 + 3/2 = 0 + 3/2

x² - 2x = 3/2

add the square of half the coefficient x to both sides:

x² - 2x + 1 = 3/2 + 1

(x - 1)² = 2.5

taking square root:

x - 1 = ±√2.5

x = 1 ± √2.5

The solution to the quadratic equation 2x² - 4x - 3 = 0 is x = 1 ± √2.5

Tell whether the ordered pair (- 3, 0) is a solution of the given system. - 2x + 2y &gt;= 4an y &gt;= 2x - 6
alukav5142 [94]

Answer:

The ordered pair is a solution.

Step-by-step explanation:

Plug x = -3 and y = 0 into the 2 inequalities and see if they fit:

-2x + 2y >= 4

-2(-3) + 2(0) = 6   which is > 4 so this one fits.

y>= 2x - 6

0 >= 2*-3) - 6 = -12 which also fits.

X3(2x2 + 3x) <br><br> a. 2x5 + 3x4 <br> b. 5x9 <br> c. 2x6 + 3x3 <br> d. 5x
Serhud [2]

Answer:

2x^5+3x^4

Step-by-step explanation:

x^3\left(2x^2+3x\right)

<u>Apply distributive law: </u>a\left(b+c\right)=ab+ac

  • x^3\left(2x^2+3x\right)=x^3\times \:2x^2+x^3\times \:3x
  • x^3\times \:2x^2+x^3\times \:3x
  • 2x^5+3x^4
