y=x^2+11x+10

Explanation:

The standard form of a quadratic equation follows the general equation:

y=ax^2+bx+c

To find the standard form of the equation, expand the brackets:

y=(color(red)x+color(blue)1)(color(orange)x+color(green)10)
y=color(red)x(color(orange)x)+color(red)x(color(green)10)+color(blue)1(color(orange)x)+color(blue)1(color(green)10)
y=x^2+10x+x+10
y=x^2+11x+10
