Question

find the sum and product of roots of the quadratic polynomial -x^2+3x-3​

Answer 1

Step-by-step explanation:

$- {x}^{2} + 3x - 3 \\ \\ - ( - {x}^{2} + 3x - 3) \\ \\ {x}^{2} - 3x + 3 \\ \\ \\ sum \: of \: zeros \: = \frac{ - (coefficient \: of \: x)}{ (coefficient \: of \: {x}^{2}) } \\ \\ = \: \frac{ - ( - 3)}{1} = 3 \\ \\ \\ product \: of \: zeros \: = \frac{constant \: term }{ \:(coefficient \: of \: {x}^{2}) } \\ \\ \frac{3}{1} = 3$
