1 answer

To rewrite the equation \( 5q^2 - 3q = 4q^2 - 5q + 15 \) in standard form, we need to move all terms to one side of the equation.

  1. Start with the given equation:
    \[ 5q^2 - 3q = 4q^2 - 5q + 15 \]

  2. Subtract \( 4q^2 \), add \( 5q \), and subtract \( 15 \) from both sides:
    \[ 5q^2 - 4q^2 - 3q + 5q - 15 = 0 \]

  3. Combine like terms:
    \[ (5q^2 - 4q^2) + (-3q + 5q) - 15 = 0 \] \[ q^2 + 2q - 15 = 0 \]

So, the equation in standard form is:
\[ q^2 + 2q - 15 = 0 \]

Now, let's solve the equation using factorization or the quadratic formula.

Factorization

  1. Find factors of -15 that add up to 2:
    The factors of -15 that work are 5 and -3.

  2. Rewrite the quadratic:
    \[ (q + 5)(q - 3) = 0 \]

  3. Set each factor to zero:
    \[ q + 5 = 0 \quad \Rightarrow \quad q = -5
    \]
    \[ q - 3 = 0 \quad \Rightarrow \quad q = 3 \]

Solutions

The solutions to the equation \( q^2 + 2q - 15 = 0 \) are:
\[ q = -5 \quad \text{and} \quad q = 3 \]

Thus, you have completed both parts: the equation in standard form is \( q^2 + 2q - 15 = 0 \) and the solutions are \( q = -5 \) and \( q = 3 \).
