y = 80x^2 +32x +30y=80x2+32x+30

Explanation:

To get the expression into standard form, expand it to get rid of all the brackets, then add like terms and order in descending order of powers.
y = (5x+2)^2 +11x(5x+2) +30y=(5x+2)2+11x(5x+2)+30
y = 25x^2 +10x + 2 +55x^2 +22x +30y=25x2+10x+2+55x2+22x+30
y = 80x^2 +32x +30y=80x2+32x+30
