Let x2+11x=3 .

What values make an equivalent number sentence after completing the square?

Enter your answers in the boxes.

x2+11x+
=

121/4 ; 133/4

Step-by-step explanation:

x² + 2(x)(11/2) + (11/2)² - (11/2)² = 3

x² + 2(x)(11/2) + (11/2)² = 3 + 121/4

x² + 11x + 121/4 = 133/4

x^2 +11x +121/4 = 133/4

Step-by-step explanation:

x^2 +11x =3

We need to complete the square

Take 11

Divide it by 2

11/2

Then square it

(11/2)^2 =121/4

Add it to each side

x^2 +11x +121/4 = 3+121/4

x^2 +11x +121/4 = 12/4+121/4

x^2 +11x +121/4 = 133/4

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
