A polynomial q(t) with sum of zeroes as 1 and the product as -6 is modelling Anu’s height in feet above the water at any time t( in seconds). Then q(t) is given by
(a) t² + t + 6
(b) t² + t -6
(c) -8t² + 8t + 48
(d) 8t² - 8t + 48
SOLUTION
(c) -8t² + 8t + 48
Explanation:
In this question The quadratic polynomial is
t² - (Sum of roots) + Product of roots
= t² - (1) + (-6)
= t² -1 -6
Now,
= -8 (t² -1 -6)
= -8t² -8 + 48
