4x * x = 4x^2

It can't be simplified any more. That is the answer, 3*4X or 12x

4x^2

4x × 4x = (4x)² = 16x²

4x

Let the unknown number be x: 4x-2 = -7 4x = -7+2 4x = -5 x = -1.25

(4x - 1)(4x + 1)

2(4x-1)=18 is the question. In this case, x=2.5

2 (2x) = 4x

Let the number be x: 4x-2 = 6x+2 4x-6x = 2+2 -2x = 4 x = -2

4x

I believe you are asking: What is the derivative (d/dx) of (4x+25)^0.5 If this is indeed the case, the derivative d((4x+25)^0.5)/dx = 0.5*(4x+25)^-0.5*4 = 2(4x+25)^-0.5 That is, 2 times the quantity (4x+25) to the negative 1/2 power.

If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6

-6x, -4x =

It is 2/(4*N)

Use the FOIL method. (4x^3 - 4)(x^2-25) 4x^3*x^2=4x^5 -4*x^2=-4x^2 4x^3*-25=-100x^3 -4*-25=100 4x^5-100x^3-4x^2+100 Factor out a 4 to simplify 4(x^5-25x^3-x^2+25)

-4x-2+2=-2+2. -4x/-4=0/-4 x=0

4cubes times 2 cubes=8cubes

4x * 3x = 12x2

4X^2 - 8X factor out 4X 4X(X - 2)

8X^2 - 4X^2 factor out a 4X^2 4X^2(4 - 1) all I can see to do
