Explain how to evaluate algebraic expression given value of a variable.

Mathematics

Marina86 [1]3 years ago

If you are given the value of a variable, all you have to do is substitute the variable for the value. For instance, if you are given an expression 2x + 5y, where x = 4 and y = 2, you evaluate the expression by substituting x with 4 and y with 2. That gives you 2(4) + 5(2) = 8 + 10 = 18

I hope this helps. Please make my answer the brainliest if you are satisfied with it.

What the factor of this? Look at picture
yulyashka [42]
X^3 - 4x^2 - 3x + 18 = 0
We are told that 3 is a zero so x - 3 is a factor. Dividing x^3 - 4x^2 - 3x + 18 by x-3 gives us a quotient of x^2 - x - 6 which factors into (x-3)(x+2).

The answer to this question is (x+2)(x-3)^2 = 0
