\bold{Hey\ there!}


  • \bold{Assuming\ you\ meant: 2x^2+28x+90=0}

  • \bold{Factor\ the\ LEFT\ side\ of\ your\ equation:}
    \bold{2(x+5)(x+9)=0}

  • \bold{Nextly,\ set\ each\ of\ your\ factors\ to\ the\ number\ zero(0)}

  • \bold{x+5=0\ or\ x+9=0}

  • \bold{Solve\ those\uparrow}

  • \boxed{\boxed{\bold{Thus,\ your \ answer\ is:x=-5\ or\ x=-9}}}\checkmark

Good luck on your assignment and enjoy your day!
