Question

If the product of zeroes of ax²-6x-6 is 4, Find the value of a . Hence find the sum of it's zeroes.​

Answer 1

Answer:

We also know that the sum of the roots of a quadratic equation is equal to \[ - \dfrac{b}{a}\] and the product of the roots is equal to \[\dfrac{c}{a}\]. It is given that the product of the roots of the polynomial \[a{x^2} - 6x - 6\] is 4. Hence, the value of a is \[ - \dfrac{3}{2}\].

Answer 2

Answer:

1. Value of a = -3/2 (-1.5)
2. Value of the sum of its zeroes is -4

Explanation:

Keep in mind these two formulas :

• Sum of the zeroes - (a+b) = -b/a

• Product of the zeroes - (a*b) = c/a
