What is 3x squared plus 5x plus 2?
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
How do you solve '3x plus 9 equals 81-5x'?
The problem '3x+9=81-5' can be solved as follows - 3x+9=81-5x Original Problem 3x=72-5x Subtract 9 from both sides of the equation 8x=72 Add '5x' to both sides of the equation x=9 Divide both sides by 8
What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
What iS 5x-7 plus 2x equals 3x-2 plus 4x?
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x

5x equals 3x plus 16?
5x = 3x + 16Taking the 3x to the left side of the equation and changing its sign5x - 3x = 162x = 16Divide by 2x = 8
What is 3x squared plus 5x plus 2?
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
How do you solve the equation 5x-93x 11 and are these simultanous equation if there are no answers on the end of each equation?
I assume you have : 5x - 9 = 3x + 11This is a single algebraic expression.Subtract 3x from both sides.5x - 9 - 3x = 3x + 11 - 3x2x - 9 = 11Add 9 to both sides :2x - 9 + 9 = 11 + 92x = 20x = 10
3x plus 6y equals 48 -5x plus 6y equals 32?
Presumably this is a simultaneous equation question in the form of: 3x+6y = 48 -5x+6y = 32 Subtract the bottom equation from the top equation in order to eliminate y. Note that 3x - - 5x is equal to + 8x: 8x = 16 Divide both sides by 8 to find the value of x: x = 2 Substitute the value of x into the original equations to find the value y: Therefore: x = 2 and y = 7
What is this quadratic equation written in standard form of x2 - 2 equals -2x2 plus 5x?
It is: 3x2-5x-2 = 0 and the value of x is -1/3 or 2 when solved
What is the slope of the equation -3x - 5x 25?
-3/4
How do you factor 5x cubed minus 3x squared plus 2x equals 0?
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
What is the value of x if 5x - 3 equals 4 - 3x?
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
3x plus 12 equals 5x-4?
This question is really asking you to find the value of x. Once you have found the x value you can prove or disprove the equation. To solve for x, isolate it in the equation. 3x + 12 = 5x +4 (Subtract 4 from both sides) 3x + 8 = 5x (Subtract 3x from both sides) 8 = 2x (divide both sides by 2) 4 = x So, if x = 4 does that prove your equation is correct? 3(4) + 12 = 24 5(4) + 4 = 24
