A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

X squared plus 2x plus 40 equals x squared-x plus 190 what is the value of x?

x^2+2x+40 = x^2-x+190Subtract x^2 from both sides2x+40 = -x+190Add x to both sides3x + 40 = 190Subtract 40 from each side3x = 150Divide both sides by 3x = 50


2x plus 3y equals 40 and -2x plus 2y equals 20?

Add the two equations you get 5y = 60 so y = 12 and x = 2


If 2x plus 2x equals 40 what does x equal?

To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)


-3x plus 40 equals 38?

-3x + 40 = 38 Subtract 40 from both sides: -3x = -2 Multiply both sides by -1: 3x = 2 Divide both sides by 3: x = 2/3


-4x2 plus 6x plus 40 equals 0?

-4x2 + 6x + 40 = 0 ∴ -2x2 + 3x + 20 = 0 ∴ -2x2 - 8x + 5x + 20 = 0 ∴ -2x(x + 4) + 5(x + 4) = 0 ∴ (5 - 2x)(x + 4) = 0 ∴ x ∈ {5/2, -4}


What is x in 2x 10 3X 50?

I have no idea because this is not an expresion. If you mean 2x+10=3x+50, this is how you do it. 1. 2x+10=3x+50 2. 10=x+50 3. -40=x 4. x=-40


If X squared plus 2x plus 40 equals x squared -x plus 190 what is the value of x?

You can find the value of x by equating the two equations.x^2+2x+40 = x^2-x +190Firstly, subtract x^2 from both sides2x+40 = -x + 190Now subtract 40 from each side2x = -x + 150Now add x to each side3x = 150Divide by 3x = 50


Solve and check 10-3x equals 2x-8x 40?

Presumably this is an equation asking you to find the value of x 10-3x = 2x-8x+40 Arrange all like terms on the left and right hand sides remembering to change signs: 8x-3x-2x = 40-10 Simplified: 3x = 30 Divide both sides by 3 for the solution: x = 10 Check that answer is correct by substituting 10 for x in the original equation.


If 5x plus 2x plus 3x plus 10x equals 140 What is x?

x=7 look at the bottom for the reason: First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21) so, 5x + 2x + 3x + 10x = 140 20x = 140 40/20 = 7 so, (5x7) + (2x7) + (3x7) + (10x7) = 140 so, 35 + 14 + 21 + 70 = 140


How can you solve this takin step by step7x-40 equals -3x?

7x-40 = -3x Add 40 and add 3x to both sides:- 7x-40+40+3x = 3x-3x+40 10x = 40 Divide both sides by 10:- x = 4


IF 7x -4 equals 3x plus 36 what is x?

7x-4 = 3x+36Add 4, it cancels out.. So,7x = 3x+40Now subtract 3x from 7x..4x = 40..40 divided by 4 is 10So, X= 10
