Ответ:
x^2 + 4x + 4
Step-by-step explanation:
(x+2)(x+2) Use FOIL (first outer inner last)
x * x = x^2
x * 2 = 2x
2 * x= 2x
2 * 2= 4
Combine like terms and put in correct form
x^2 + 4x + 4
Ответ:
Step-by-step explanation:
-2/3 * 5 1/6 step 1correct
(-2/3 * 5) + (-2/3 * 1/6)his error is here...it should be like I have written it, but Calvin is getting his addition and multiplication mixed up
-10/3 + (-1/9) =
-30/9 - 1/9 =
-31/9 =
- 3 4/9
so he messed up in step 2
he is doing this : (-2/3 + 5) * (-2/3 + 1/6)...when he should be doing this :
(-2/3 * 5) + (-2/3 * 1/6)
