Identify the correct list of coefficients for the quadratic expression: 3x^2 + 5x - 12

Answer 1

The coefficients of the quadratic expression $3x^2+5x-12$ can be identified as follows:

• The coefficient of $x^2$ (the quadratic term) is $3$.
• The coefficient of $x$ (the linear term) is $5$.
• The constant term (the term without $x$) is $-12$.

Therefore, the list of coefficients is:

• $a=3$ (for $x^2$)
• $b=5$ (for $x$)
• $c=-12$ (constant term)

So, the coefficients are $(3,5,-12)$.
