Can someone help with algebra x plus 4 x-4 parentheses before and after both x's and 4's?
(x + 4) (x - 4) = x2 - 16To work this out you need to multiply each term in the first bracket by each term in the second bracket.So you would do x times x which gives you x2.Then x times -4 which is -4x.Then 4 times x which 4x. (Note: this 4x will cancel out the -4x)And finally 4 times -4 which is -16.So you end up with x2 - 4x + 4x - 16 which equals x2 - 16.

What is x2-16x times x plus 4?
They are 4 terms of an expression that can be simplified to: 4 -15x^2
The expression x2 plus 4 can it be factored yes or no?
Yes. x2 + 4 = ( x + 2i ) times ( x - 2i ) where 'i' = the unit imaginary number = the square root of -1.
What is x times x plus 4?
x(x+4) equals x2 plus 4x
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
25 divided by 5 x2 -4 times 3?
the awnser is 18.. i think..
What is x to the 2nd power -3x plus2 times x minus 2?
Hmm - you need to phrase your question a little better. Which of these are you looking for? x2 - 3x + 2x - 2 = x2 - x - 2 = (x - 2)(x + 1) x2 - (3x + 2)(x - 2) = x2 - 3x2 + 6x - 2x + 4 = -2x2 + 4x + 4 = -2(x2 - 2x - 2) x2 - 3x + 2(x - 2) = x2 + x - 4
What is the answer to expand x2(x-4)?
