starting with (x+3)+(2x-1)+(x-1)
when this problem is written in a linear form it ends up being quite simple, you just have to combine like terms. Eliminating the parenthesis you get
x+3+2x-1+x-1
now group like terms together
x+2x+x+3-1-1
and solve to get 4x+1

What is the value of x6 plus 2y if x 3 and y 1?
Replace the letters by the values, remembering that when a letter is next to another or a number it means multiply; thus: x^6 + 2y =3^6 + 2x1 = 731. (if x6 is intending to mean x^6).
How are fractional exponents and radicals are related?
Here are some examples. x1/2 = square root of x; x1/3 = cubic root of x; in general, x1/n = nth root of x. Also, x2/3 = the square of the cubic root of x, or equivalently, the cubic root of the square of x.
What is another way to express the third root of x?
x1/3
What is the degree of the polynomial 2x plus 5?
The degree of the polynomial 2x + 5 is 1. The highest power of x is x1, i.e. 2x1 + 5x0, hence the designation of first degree.
X plus one over x squared plus two?
it equals x1 it equals x1
What is the name of the following math law 2 x 1 3 2x1 2x3?
2x (1+3)=(2x1+(2x3)
What is X3 plus X2 plus X plus 1 divided by X 1?
2x2+7/x1
X2 plus 6x plus 9 equals 49?
x²+6x+9=49 x²+6x-40=0 x1=-6/2 - Square root of ((6/2)²+40) x1=-3 - 7 x1= -10 x2=-6/2 + Square root of ((6/2)²+40) x2=-3 + 7 x2= 4
What is the derivative of x times root x?
x*x1/2= x3/2 Derivative = 3/2 * x1/2
What is x squared plus five x minus fourteen?
The answer is: X1 = 2 X2 = -7
How do you construct the Lagrange interpolation for a polynomial cosx plus sinx given the four values of x?
Construct the Lagrange interpolating polynomial P1(x) for f(x) = cos(x)+sin(x) when x0 = 0; x1 = 0:3. Find the absolute error on the interval [x0; x1].

Simplify The Square root of x divided by x?
sqr.rtx/x= sqrt.x*sqr.rtx/sqr.rtx=x/x*sqrt.x=1/sqrt.x. x1/2 = x1/2 * x1/2 = x = 1 (x1/2) /x= 1/x1/2
