Question

Find a quadratic polynomial
whose Zeroes are 4+√b and (4-​

Answer 1

Answer:

Step-by-step explanation:

a) we know a polynomial is of the form x^2-(α+β)x+ αβ;

where α and β are the roots

Therefore polynomial is x^2 - 4x + 1

b) if zeroes are 4 & 5, polynomial becomes (x-4)*(x-5)

= x^2 -9x+20
