Question

write a quadratic polynomial, sum of whose zeroes is 5 and product is -2 (full explain this question)​

Answer 1

Step-by-step explanation:

$sum \: of \: zeroes(a + b) = 5 \\ product \: of \: zeroes(a \times b) = - 2 \\ polynomial \: \\ {x}^{2} - (a + b)x + a \times b = 0 \\ {x}^{2} - 5x + ( - 2) = 0 \\ {x}^{2} - 5x - 2 = 0$

Answer 2

Answer:

thus the required quadratic equation is X square minus five X minus 2
