Question

Find a quadratic polynomial each with the given numbers as the sum and product

of its zeroes respectively. (i) ¼, -1 (ii) 4, 1​

Answer 1

sum of zero es = 1/4 +-1 = -3/4

product of zeros = 1/4

x²-(a+b)+ab = x² +3/4x + 1/4 = 4x² +3x+1

sumof zeros = 4+1=5

product of zeros= 4

x²-(a+b)+ab = x²-5x+4
