Question

can you walk me through
2(x+2)^2 +3

Answer 1

PEMDAS do u know what that is

Answer 2

\[2(x+2)^2 +3\]

Answer 3

\[2x^2+8x+8+3\]

Answer 4

ya after you distribute the square where do you go

Answer 5

its not 8x its 16x

Answer 6

\[(2x^2)+(8x)+(8+3)\]

Answer 7

its not (8x) because 2 x 2 = 4 then 4 x 4

Answer 8

\[2(x^2+2^2)+3\]

Answer 9

right?

Answer 10

no it would be ( 2x + 4) ^2 +3 then go from there

Answer 11

then I have 2x^2+8+3 or 2x^2+11

Answer 12

no its not because e2x^2 is 2x times 2x so 4x^2 + 16 + 3

Answer 13

the power of two means double the same number not times 2

Answer 14

so it would be 4 times 4 = 16

Answer 15

4x+19

Answer 16

yes then 4x= -19

Answer 17

find x

Answer 18

2(x+2)^2 +3 =
2(x^2 +4x +4) +3 =
2x^2 +8x +8 +3 =
2x^2 +8x +11

@Awolflover1 your result is right sure

Answer 19

so what you need to do - solve it for x ?

in this case discriminant = 64-88=-24 <0 what mean that have not real roots

hope helped
