Question

if a and b are zeroes of polynomial x^2 -2x+5 find the quadratic polynomial whose zeroes are a+ b and 1/a +1/b​

Answer 1

Explanation:

Compare with x²-Sx+P, a+b=2, ab=5

1/a +1/b = (a+b)/ab=2/5

Sum of roots = 2+2/5 = 12/5

Product = 2(2/5)=4/5

Polynomial is x²-(12/5)x + 4/5

Answer 2

Answer:

If the zeroes of the quadratic polynomial x2

+ (a + 1) x + b are 2 and -3, then

first put 2 in x then make equation 1, then put -3 in x and then make equation 2, by using substitute method, answer will be there
