The simplified form for (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y) is (5x² + 0y² - 10x + 4y - 2xy).
<h3>A quadratic equation is what?</h3>
At least one squared term must be present because a quadratic is a second-degree polynomial equation. It is also known as quadratic equations. The answers to the issue are the values of the x that satisfy the quadratic equation. These solutions are called the roots or zeros of the quadratic equations. The solutions to the given equation are any polynomial's roots. A polynomial equation with a maximum degree of two is known as a quadratic equation, or simply quadratics.
<h3>How is an equation made simpler?</h3>
The equation can be made simpler by adding up all of the coefficients for the specified correspondent term through constructive addition or subtraction of terms, as suggested in the question.
Given, the equation is (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y)
Removing brackets and the adding we get,
3x² + 2x² + 2y² - 2y² + (- 5x) + (- 5x) + y + 3y + (- 2xy) = (5x² + 0y² - 10x + 4y - 2xy)

Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.
1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x
2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2
The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.

To find the area of a circle.
We first need the radius.
This is quite simple, the radius is half of the diameter
Knowing the diameter is 14
14 divided by 2 = 7.
Now for a circle here is the equation
A = Area
A = <span>π r ^2
</span>
So we have the radius being 7 but now it needs to be squared.
7 x 7 = 49.
So now our equation is.
A = <span>π 49 ^2 (Keep in mind ^2 is just squared)
</span>
Now this is the answer but we can get more technical by multiplying 49 times <span>π
</span>
Now <span>π equals roughly 3.14
</span>
So we can do 49 x 3.14 cm
Which this equals 153.86
Which rounding to the nearest tenth gets you:
153.9 cm is your area
I really do hope this helps!
