the zeroes of quadratic polynomial x^2 + 1750x + 175000 are.....
a) both negative b) one positive one negative
c) both positive d) both equal
explain the ans with solution plzzzzzzzzzzz
(A) both negative
TO calculate how many positive zeros or roots, we just have to see the change in sign. No of times of change in sign value from positive to negative and from negative to positive is the number of maximum positive roots. If there is change in sign 3 times means there can be at most 3 positive roots.
In your case, there is no change in sign, so no positive roots.
Therefore all negative
