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

    Step-by-step 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+(\frac{b}{2})^2 =35+(\frac{b}{2})^2

    x^2+2x+(\frac{2}{2})^2 =35+(\frac{2}{2})^2

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