Question

9x2 + 49x = 22 − 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 Which is the best step to do next to solve the equation by completing the square?

Answer 1

it may be 9(+6x+9)=103 i may be wrong

Explanation:

Answer 2

Next Step Is 9(
`x^(2)`+6x+9)=103

Explanation:

9
`x^(2)`+49x=22-5x

9
`x^(2)`+54x=22

9(
`x^(2)`+6x)=22

now to turn the equation into a perfect square , we must add 81 on both sides

9(
`x^(2)`+6x)+81=22+81

9(
`x^(2)`+6x+9)=103 :- [
`(x+3)^(2)`=
`x^(2)`+6x+9]
