Question

expand using formula (x+2)(x+3)​

Answer 1

Answer:

The method that many use is called F.O.I.L. (first, outer, inner, last).

Start with multiply the First items X*x = x^2

Then the Outer: x*3 = 3x

Inner 2*x = 2x

Last: 2*3=6

Put them all together and you have x^2 + 3x + 2x +6

Simplify by grouping any like terms (in this case 3x and 2x) and add them (5x in this case).

You end up with x^2 + 5x + 6.

Questions like this won’t necessarily display in the order that you wish. Convention is to give the answer so that the x’s with the highest exponent (in this case, the power of 2) are on the left, then the x’s (effectively x^1) and then any numbers. Displaying in another order isn’t actually wrong, but it’s often better to keep with convention for the sake of clarity.
