Question

If the sum of the product of the zeroes
taken two at a time of the polynomial
f(x) = 2x - 3x² + 4tx - 5 is -8, then the
value of t is​

Answer 1

Answer:

- 4

Step-by-step explanation:

The sum of the zeroes of the equation ax + bx² + cx + d is c / a

Here the equation is 2x - 3x² + 4tx - 5

a = 2

b = -3

c = 4

d = -5

Sum of roots = 4t / 2

⇒ 4t / 2 = -8

⇒ 4t = -8 × 2

⇒ 4t = -16

⇒   t = -16 / 4

⇒   t = -4

∴ The value of t is equal to -4.
