What are quadratic roots

1 answer:

4 0

This may help, a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term.
here’s an example

The equation y=7.6x represents a proportional relationship what is the constant of proportionality?

prisoha [69]

Answer:

Option B. 7.6

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

where

k is the constant of proportionality

The slope of the linear equation is the same that the constant of proportionality

In this problem we have

$y=7.6x$

the slope is $m=7.6$

therefore

The constant of proportionality k is $k=7.6$

$=\dfrac{1}{x+2}\cdot\dfrac{x-5}{x-5}+\dfrac{6}{x-5}\cdot\dfrac{x+2}{x+2}\\\\=\dfrac{1(x-5)+6(x+2)}{(x+2)(x-5)}\\\\=\dfrac{7x+7}{x^{2}-3x-10}$

Usually, the "simplified" form has the polynomial multiplied out (as immediately above), rather than factored. If you want it factored, you can remove a factor of 7 from the terms of the numerator to get 7(x+1)/((x+2)(x-5)).
