Given y = (2x 3)2, choose the standard form of the given quadratic equation. 0 = 25x2 0 = 4x2 9 0 = 4x2 10x 6 0 = 4x2 12x 9

With the given expression in the problem y=(2x+3)², we can solve for the standard form of an equation.

To recall, the standard form is:
f(y) = ax² + bx + c

Solving for the standard form:
y = (2x + 3)²
y = (2x +3) (2x+3)
y= 4x² + 6x +6x+9
y= 4x² +12x +9

The standard form is f(x) =  4x² +12x +9.
