The equation that has an a value of 1, b value of -3 and c value of -5 is f(x) = x² -3x - 5
Quadratic equation
These are equation that has a leading degree of 2. The standard quadratic equation is expressed as:
f(x) = ax² + bx + c
Given the following coefficients
Substitute the coefficients into the formula to have;
f(x) = 1x² + (-3)x + (-5)
f(x) = x² -3x - 5
Hence the equation that has an a value of 1, b value of -3 and c value of -5 is f(x) = x² -3x - 5
