To combine y^2 and 6y, you need to determine if they have any common factors. In this case, they do not have any common factors, so you cannot directly combine them. The expression y^2 + 6y is already simplified and cannot be further combined without additional terms or operations.

Multiply and simplify y-6 y-4?
(y-6)(y-4) y x y = y2 y x -4 = -4y y x -6 = -6y -4 x -6 = 24 y2 - 4y - 6y + 24 y2 - 10y + 24
What is Y if Y2 plus 6y-9 equals 0?
Y = 1.125 2Y + 6Y - 9 = 0 2Y + 6Y = 9 Y(2+6) = 9 8Y = 9 Y = 9/8 = 1 1/8 = 1.125 PROOF: 2(1.125) + 6(1.125) - 9 = 0 2.5 + 7.5 - 9 = 0 9 - 9 = 0
How do you FOIL a math problem witha binomial and a trinomial?
FOIL is an acronym standing for first, outside, inside, and last, which is a method for multiplying binomials For example: (a + b)(a + b) F (a + b)(a + b) = a2O (a + b)(a + b) = +abI (a + b)(a + b) = +abL (a + b)(a + b) = b2 a2 + ab + ab + b2 = a2 + 2ab + b2 *always remember to watch the signs. If you multiply -a times b you get -ab. Also, remember to add or subtract the coefficients (Coefficients are the numbers in front of the variables. If no number is seen, it is automatically a 1. The coefficient of -ab is -1 and the coefficient of ab is 1, thus ab + ab = 2ab). Multiplying binomials and trinomials is similar, but FOIL is not used. There are various methods used, here is one of them: Example 1 (x + 3)(x2 - 3x - 5) Step 1: Multiply x by the entire trinomial (x + 3)(x2 - 3x - 5) = x3(x + 3)(x2 - 3x - 5) = -3x2(x + 3)(x2 - 3x - 5) = -5x Step 2: Multiply 3 by the entire trinomial. Remember to keep the signs, or in other words, remember that 3 is positive. (x + 3)(x2 - 3x - 5) = +3x2(x + 3)(x2 - 3x - 5) = -9x(x + 3)(x2 - 3x - 5) = -15 The product looks like: x3 - 3x2 - 5x + 3x2 - 9x - 15 Step 3: Combine like terms or simplify x3 - 14x - 15 Remember that terms are ordered by the highest power to the lowest power. Example 2(2y - 3)(y2 + 6y + 10) Step 1: (2y - 3)(y2+ 6y + 10) = 2y3(2y - 3)(y2 + 6y + 10) = +12y2(2y - 3)(y2 + 6y + 10) = +20y Step 2: (2y - 3)(y2 + 6y + 10) = -3y2(2y - 3)(y2 + 6y + 10) = -18y(2y - 3)(y2 + 6y + 10) = -30 = 2y3 + 12y2 + 20y - 3y2 - 18y - 30Step 3: 2y3 + 9y2 + 2y - 30
What is the answer to 1 plus 6y?
That is the answer. If y is undefined, then 1+6y is as far as you can go.
What is 6y - 8y?
-2
