Question

from the quadratic equations from the roots 3and -10 <br />explanation​

Answer 1

Answer:

x² + 7x - 30

Step-by-step explanation:

Let,

α = 3

β = - 10

α + β = 3 - 10

α + β = - 7

αβ = 3 ( - 10 )

αβ = - 30

x² - ( α + β )x + αβ = 0

x² - ( - 7 )x + ( - 30 ) = 0

x² + 7x - 30 = 0

Therefore, the quadratic equation is x² + 7x - 30.
