Find the Coefficient of x in y=3x²+10-x: Identifying Linear Terms

To solve this problem, we need to identify the coefficient of $x$ in the given quadratic equation. The equation given is $y = 3x^2 + 10 - x$. Let’s rearrange this equation to match the standard form of a quadratic equation $ax^2 + bx + c$.

The given equation can be rewritten as:

$y = 3x^2 - x + 10$

Here, we can identify the coefficients:

• $a = 3$ (for $x^2$)
• $b = -1$ (for $x$)
• $c = 10$ (the constant term)

Therefore, the value of $b$, the coefficient of $x$, is $-1$.
