<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
She wants to buy a sofa for $924 and a coffee table for $640, hence:
Estimated total cost = 924 + 640 = $1564
The Estimated total cost was $1564. Zara do not have eough money to buy the sofa and coffee table.

First you rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Second you solve it by using the formula of a straight line drawn on Cartesian coordinate system in which “y” is the vet risk axis and “x” the horizontal axis.

Step-by-step explanation:
Answer:
x = 2 + √2
x = 2 - √2
Step-by-step explanation:
- x² + 2x + 1 = 0
x² - 2x - 1 = 0
Here,
a = <em>1</em>
b = <em>- 2</em>
c = <em>- 1</em>
Now,
Discriminant
D = b² - 4ac
= (-2)² - 4(1)(-1)
= 4 + 4
= 8
=2√2 > 0
<em><u>Real and </u></em><em><u>D</u></em><em><u>istinct roots </u></em>
x = - b +- √b² - 4ac/2a
= - (-2) +- √ = (-2)² - 4(1)(-1)/2(1)
= 2 +- √4 + 4/2
= 2 +- √8/2
= 2 +- 2√2/2
= 2 +- √2
x = 2 + √2 or x = 2 - √2
