Please can you expand and simplify the following:

(2x-5)(x+3)

Many thanks.

Happy New Year

Learn and apply the FOIL method.

(First, Outside, Inside, Last)
That describes the pairs of terms that you must multiply and then add together.

To learn algebra, you really need the practice doing this yourself

surely, it would be x^3-2x-15

please correct me if i'm wrong

Chelsea is wrong. Only the -15 term is correct. There is no cubic (x^3) term

i looked at the site, now i'm really confused, could you just show me the answer and working out, we haven't done the foil method in school we do it differently.

What you are doing in school must be the same thing, perhaps with a different name.

Why do you keep changing your name?
When you multiply the first pair you get
2x * x = 2x^2
That is the first term.
When you multiply the "inside" pair you get -5x
Now you do the others and combine terms.

The answer you should get is

2x^2 +x -15

To expand and simplify the expression (2x - 5)(x + 3), we can apply the distributive property.

Step 1: Multiply the first terms in each binomial:
First term = 2x * x = 2x^2

Step 2: Multiply the outer terms in each binomial:
Outer term = 2x * 3 = 6x

Step 3: Multiply the inner terms in each binomial:
Inner term = -5 * x = -5x

Step 4: Multiply the last terms in each binomial:
Last term = -5 * 3 = -15

Now, combine all the terms:

2x^2 + 6x - 5x - 15

Simplifying further, we can combine like terms:

2x^2 + (6x - 5x) - 15
2x^2 + x - 15

Therefore, the expanded and simplified form of (2x - 5)(x + 3) is 2x^2 + x - 15.

Happy New Year to you too!
