What would I get by solving by polynomials?

x=0 or x=3 or x= -3⅘

Step-by-step explanation:

Please see attached picture for full solution.

Another way to solve it is to factorise x out from the equation from the beginning. This would leave you with

x(5x² +4x -57x)=0

Then you can factorise the quadratic equation.

x(x -3)(5x +19)= 0

And solve it just like we did above.

x=0 or x-3=0 or 5x+19=0

x=3 or 5x= -19

x= -3⅘

In the picture, I used synthetic division but long division works too!

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
