How to Write the Expression x² + 6x + 7 in the Form x² + ax + b?

In our expression, we already have it structured as follows:

• x²: This is our quadratic term.
• 6x: This is the linear term, where the coefficient is 6.
• 7: This is the constant term.

This means we can directly identify:

• a = 6
• b = 7

Thus, the expression x² + 6x + 7 is already in the required form of x² + ax + b, where a = 6 and b = 7.
