प्रश्न
If (a-b) , a and (a + b) are zeros of the polynomial `2x^3-6x^2+5x-7` write the value of a.
उत्तर
By using the relationship between the zeroes of the quadratic polynomial.
We have
Sum of zeroes = `(-("Coefficient of" x^2))/("Coefficient of "x^3)`
`a – b + a + a + b =(-(-6))/2`
⇒ 3a = 3
⇒ a = 1
