If the quote is not enough for them, you can try this:
I posted on the fridge that I would pay each of my children every day in dollars: X squared -19X + 90, when X= (or is greater than)$10.
They asked, "For real?" Sure!
Then they worked it out.
Using 10 we get: 100 -190 +90= 0
Using 100 we get: 1000 - 1900 +90= -$810
That's right, if they decide to let X= $100 dollars, they could each pay me $810. Every day.
You need algebra to survive around here!

Thanks for sharing this and I am here to discuss about algebra that is,Algebra is the most important and simple topic in mathematics, Its a branch of mathematics that substitutes letters in place of numbers means letters represent numbers and In algebra 2 we study many things like complex number system change in symbols and functions etc.
