YES!
A polynomial is made up of terms that are only added, subtracted or multiplied. Division is not allowed.
It may have constants, exponents or variables. A monomial is one type of polynomial.
y+2y is the same as 4y which is a monomial. It has degree 1 since the exponent on y is 1.
2y(3x + 1)
It is y+3y-2y = 2y simplified
It is an ordinary linear equation. Divide by 2, solving for y, and you get y = 1.5x. This is a straight line that goes through the Y intercept 0, with a slope of 1.5.
5+y+2y? = 5+3y?
2y + 7x + y-1?
2y(3x + 1)
-2y+y = -y
2y
(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
It is y+3y-2y = 2y simplified
5+y+2y? = 5+3y?
2y + 7x + y-1?
It is an ordinary linear equation. Divide by 2, solving for y, and you get y = 1.5x. This is a straight line that goes through the Y intercept 0, with a slope of 1.5.
Y plus Y = 2Y simplified
