Specific Algebra Task: Create an Expression with a = -3, b = 15, c = 0

Create an algebraic expression based on the following parameters:

$a=-3,b=15,c=0$

To solve this problem, we will follow these steps:

• Step 1: Substitute the given values $a = -3$, $b = 15$, and $c = 0$ into the quadratic formula $ax^2 + bx + c$.
• Step 2: Simplify the expression, removing any terms where the coefficient is zero.

Let's apply these steps:

Step 1: Start with the standard form of a quadratic expression $ax^2 + bx + c$. Given $a = -3$, $b = 15$, and $c = 0$, substitute these values:

$y = -3x^2 + 15x + 0$

Step 2: Simplify the expression:

The term $+0$ can be removed because it does not affect the value of the expression, leading to:

$y = -3x^2 + 15x$

Thus, the algebraic expression based on the parameters provided is $-3x^2 + 15x$.

Among the given choices, the correct choice is:

• Choice 4: $-3x^2 + 15x$
