Question

Form a quadratic polynomial whose zeroes are (i) - 5 and 4

Answer 1

sum of zeroes = -1



product of zeroes = -20



x ^2 - ( -1 ) + ( - 20 )


x ^2 +1 -20

Answer 2

Sum of zeroes= -1

Product of Zeroes= -20

Therefore, the quadratic polynomial

i.e x²- (sum of zeroes)x+(product of zeroes)

= x² - (-1)x + (-20)
= x² + x -20
