Hey there!


\bold{x^2-10+25=35}

Firstly, we have to to simplify both sides of your equation


  • \bold{x^2-10+25=35}

  • \bold{-10+25=15}
  • Firstly, now that we got that portion out the way, let's
    \bold{subtract} by the number
    \bold{15} on each of your sides

  • \bold{x^2+15-15=35-15}

  • \bold{Cancel:15-15}

  • \bold{Keep:35-15}

  • \bold{35-15=20}
  • We get:
    \bold{x^2=20}
  • Take the square root of the number

  • \bold{x=}±
    \bold{√(20)}

  • \boxed{\boxed{\bold{Answer:x=2√(5)[or]x=-2√(5)}}}
    \checkmark

Good luck on your assignment and enjoy your day!
