Question

Rewrite the equation by completing the square x^2+2x-35=0

Answer 1

1 for the first box and 35 for the second one.

Explanation:

Answer 2

Answer:
`x^2+2x+1=36`

Explanation:

`x^2+2x-35=0`

add 35 on both sides.

`x^2+2x-35+35=0+35`

`x^2+2x=35`

take the value of b (2) divide it by 2 and square it.

`x^2+2x+((b)/(2))^2 =35+((b)/(2))^2`

`x^2+2x+((2)/(2))^2 =35+((2)/(2))^2`

`x^2+2x+(1)^2=35+(1)^2\\x^2+2x+1=35+1\\x^2+2x+1=36`
