Solving quadratic equations is one of the main topics of this unit. Some quadratic equations can be solved with only one method,
Mariana [72]

Hi there!

Many things we do in everyday life have a variety of ways we can go about accomplishing them, but we most often choose the most practical and efficient method.

Efficiency saves time and prevents over-complication, which may lead to errors.

We might need to identify the specifics of the task and its circumstances to be able to determine the most efficient method to do it.

Solving a quadratic equation, we also must think about the most efficient method that can lead us to the correct answer. And doing so, we must identify the circumstances of the equation; Can it be solved by factoring? Is it easy to factor? What form is this quadratic equation in?

For example, let's say we're given the equation (x-1)(x+2)=0. This is an equation in factored form. In these kinds of scenarios, we can <em>easily</em> solve by setting each term equal to 0 (the Zero Product Property). This is the <em>most efficient </em>method:

x-1=0 --> x=1

x+2=0 --> x=-2

I hope this helps!

If the , points on the graphs are (-4,1) and (2,1) what is the equation ?
balandron [24]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept


To find "m", you can use the slope formula and plug in the two points:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{1-1}{2-(-4)}

m=\frac{1-1}{2+4}

m=\frac{0}{6}=0


The slope is 0 so:

y = mx + b

y = 0x + b     [any number multiplied by 0 is 0]

y = b      

To find "b", you plug in either of the points into the equation (since both of their y values are 1]

y = b

1 = b


Your equation is:

y = 1      (This is a horizontal line)

6=m-7/8<br> please help me pleaaaaaaaase
AlladinOne [14]

Answer:

m = 55/8 = 6.875

Step-by-step explanation:

Step by step solution :

Step  1  :

           7

Simplify   —

           8

Equation at the end of step  1  :

            7

 6 -  (m -  —)  = 0  

            8

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  8  as the denominator :

         m     m • 8

    m =  —  =  —————

         1       8  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
