Answer:
[tex]x^2 -2x -15=0[/tex]
Step-by-step explanation:
[tex]\text{Given that, the roots are,}~ \alpha=-3 ~ \text{and}~ \beta=5 .\\\\\text{The quadratic equation with roots}~ \alpha ~ \text{and}~ \beta ~ \text{is,}\\\\~~~~~~~~x^2 - (\alpha + \beta )x +\alpha \beta = 0\\\\\implies x^2-(-3 +5) x +(-3)(5) = 0\\\\\implies x^2 -2x -15=0[/tex]
Answer:
x²-2x-15=0
Step-by-step explanation:
x=-3 x=5
x+3=0 x-5=0
(x+3)(x-5)=0
x²-5x+3x-15=0
x²-2x-15=0
