4x x to second power - 4x plus 3 equals 0?

Given, 4x2 - 4x + 3 = 0; then, 4x2 - 4x + 1 = (2x - 1)2 = -2, 2x - 1 = √-2 = ±i√2, and 2x = 1 ± i√2; therefore, x = ½(1 ± i√2).


What the Anserw to 4x plus 1 equals 2x plus 5?

4x + 1 = 2x + 5 4x + 1 - 2x = 2x + 5 - 2x 2x + 1 = 5 2x + 1 - 1 = 5 - 1 2x = 4 2x/2 = 4/2 x = 2


How do you solve 2x equals 4x plus 1?

2x = 4x +1 2x-4x = 1 -2x = 1 x = - 1/2 check Leftside = 2 (- 1/2) = -1 Right side = 4 (- 1/2) +1 = -2 + 1 = 1 - 2 = -1 LS = RS therefore x = - 1/2


How do you solve 2x-5 equals 4x-1?

you want to put all of the 'x' on one side and all of the numbers on the other side 2x-5=4x-1 2x-5 (-2x +1) = 4x -1 (-2x + 1) -4 = 2x then divide by 2 x=-2


What are the points of intersection of the equations x2 -xy -y2 equals -11 and 2x plus y equals 1?

If: 2x+y = 1 then y = 1-2x and y^2 = (1-2x)^2 which is 1-4x+4x^2 If: x^2 -xy -y^2 = -11 then x^2 -x(1-2x) -(1-4x+4x^2) = -11 So it follows: x^2 -x +2x^2 -1 +4x -4x^2 +11 = 0 Collecting like terms: -x^2 +3x +10 = 0 Factorizing the above: (x-5)(-x-2) = 0 meaning x = 5 or -2 Points of intersection by substitution are at: (5, -9) and (-2, 5)


What must be subtracted from 4x power 4 so that the result is exactly divisible by 2x power 2 plus x-1?

NOT CALCULUS. Use long division. 2x2 + x - 1(4x^4) 2x^2 goes into 4x^4 2x^2 times. The remainder will then be (2x^2*(x-1)). This result(2x^3 - 2x^2) is what need to be subtracted from 4x^4 to make it exactly divisible


What are the points of contact between the equations of x2 plus xy plus y2 equals 7 and 2x plus y equals 1?

If: 2x+y = 1 then y = 1-2x If: y^2 = (1-2x)^2 then y^2 = 1-4x+4x^2 If: x^2 +xy +y^2 =7 then x^2 +x(1-2x) +1-4x+4x^2 = 7 So it follows: x^2 +x-2x^2 +1-4x+4x^2 -7 = 0 Collecting like terms: 3x^2 -3x -6 = 0 Dividing all terms by 3: x^2 -x -2 = 0 Factorizing the above: (x+1)(x-2) = 0 meaning x = 2 or -1 By substitution points of contact are made at: (2, -3) and (-1, 3)


When x3 plus 3x2-2x plus 7 is divided by x plus 1 what is the remainder?

(x3 + 3x2 - 2x + 7)/(x + 1) = x2 + 2x - 4 + 11/(x + 1)(multiply x + 1 by x2, and subtract the product from the dividend)1. x2(x + 1) = x3 + x22. (x3 + 3x2 - 2x + 7) - (x3 + x2) = x3 + 3x2 - 2x + 7 - x3 - x2 = 2x2 - 2x + 7(multiply x + 1 by 2x, and subtract the product from 2x2 - 2x + 7)1. 2x(x + 1) = 2x2 + 2x2. (2x2 - 2x + 7) - (2x2 + 2x) = 2x2 - 2x + 7 - 2x2 - 2x = -4x + 7(multiply x + 1 by -4, and subtract the product from -4x + 7)1. -4(x + 1) = -4x - 42. -4x + 7 - (-4x - 4) = -4x + 7 + 4x + 4 = 11(remainder)

How do you find value of unknown number 4x plus 1 equals 2x-3?

We can solve this by following the steps I'm about to explain. 1) Write the equation out. • 4x + 1 = 2x - 3 2) Get the numbers and variables to their own side. • 4x + 1 = 2x - 3 • 4x + 1 - 1 = 2x - 3 - 1 • 4x = 2x - 4 • 4x - 2x = 2x - 2x - 4 • 2x = -4 3) Perform the opposite operation that is holding the variable together. (2x = 2(x) so we're multiplying - we need to divide) • 2x = -4 • 2x/2 = -4/2 • x = -2 4) Check your solution • 4x + 1 = 2x - 3 Substitute the value of X for every x in the equation. • 4(-2) + 1 = 2(-2) - 3 • -8 + 1 = -4 - 3 • -7 = -7


What is the answer to this equation 4x plus 2 plus 2x-2x equals 14?

4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3


Factor 4x -2x - 12?

As written, that's 2(x - 6) You may have meant 4x^2 - 2x - 12 which would be 2(2x + 3)(x - 2)


What is x when 2x equals 4x plus 3?

2x = 4x + 3 -2x = 3 x = -3 / 2


What is the answer 8x2-2x-3 equals 0?

8x2-2x-3=0 (2x+1)(4x-3)=0 2x+1=0 or 4x-3=0 x=-1/2 or x=3/4


2x equals x2 plus 4x-3?

2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0


How do you simplify y equals 2x-5 and 4x-y equals 7?

y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3


How do you simplify 3x-4x plus 9x-x?

What are the solutions to the simultaneous equations of x squared plus xy plus y squared equals 7 and 2x plus y equals 1 showing work?

If: 2x+y = 1 Then: y = 1-2x If: x^2 + xy + y^2 = 7 Then: x^2 +x(1-2x) +(1-2x)^2 = 7 So: x^2 +x-2x^2 +1-4x+4x^2 -7 = 0 Collecting like terms: 3x^2 -3x -6 = 0 Divide all terms by 3: x^2 -x -2 = 0 Factorizing (x+1)(x-2) = 0 => x = -1 or x = 2 Solutions by substitution: (-1, 3) and (2, -3)
