Answer:
I think it is useless
- Learn this XD Answer :
- m = -24
- Step-by-step explanation :
- α and β are the roots of x² + 5x + m = 0
- x² coefficient = 1
- x coefficient = 5
- constant term = m
- RELATIONSHIP BETWEEN ZEROES AND COEFFICIENTS :
- ⇒ Sum of zeroes = -(x coefficient)/x² coefficient
- α + β = -5/1
- α + β = -5
- ⇒ Product of zeroes = (constant term)/x² coefficient
- α × β = m/1
- αβ = m
- 2α + 5β = -1
- 2α + 2β + 3β = -1
- 2(α + β) + 3β = -1
- 2(-5) + 3β = -1
- -10 + 3β = -1
- 3β = 10 - 1
- 3β = 9
- β = 9/3
- β = 3
- ⇒ α + β = -5
- α + 3 = -5
- α = -5 - 3
- α = -8
- We got, αβ = m
- m = α × β
- m = (-8) × 3
- m = -24
- ∴ The value of m is -24
