Just check with wolfram alpha: 4 x^3 -2x +2

[@alannahdunstan3415]

If u have plus between the set brackets is it the same as the minus sign meaning negative 1

[@drgatsis]

Yes Alannah! The negative 1 then multiplies all the terms in the brackets to its right.

[@SILICONALI420001]

If :4(x-2)(×+3) how is 4(3) 12x when there is no x

[@drgatsis]

You can think of it this way: 4 is going to multiply the x and the -2. And those answers will multiply the x and the 3. You could draw a tree diagram. So the possibilities are 4(x)(x) , 4(x)(3), 4(-2)(x) and 4(-2)(3). The second product shows you the 12x :)
