Answer:
a = 5, b = -3 and c =1
Step-by-step explanation:
The standard form of a quadratic equation is expressed as;
f(x) = ax² + bx + c
Given the expression
f(x) = 5x² = 3x - 1
f(x) = 5x² - 3x + 1
Comparing with the general formula;
ax² = 5x²
a = 5
bx = -3x
b = -3
c = 1
Hence a = 5, b = -3 and c =1
