To express the given equation \( x^2 - 7x = 4 \) in standard quadratic form \( ax^2 + bx + c = 0 \), we need to rearrange it by subtracting 4 from both sides:
\[ x^2 - 7x - 4 = 0 \]
Now, we can identify the coefficients \( a \), \( b \), and \( c \):
- \( a = 1 \) (the coefficient of \( x^2 \))
- \( b = -7 \) (the coefficient of \( x \))
- \( c = -4 \) (the constant term)
Thus, the values are:
- \( a = 1 \)
- \( b = -7 \)
- \( c = -4 \)
