Given: roots of the equation are -3 and -7

              That is α = -3  β = -7

To find: form quadratic equation

Step-by-step explanation:

We can write quadratic equation using its root as

 x² + ( α+β )x + αβ = 0

⇒  x² + ( -3-7 )x + ( -3×-7 ) = 0

⇒  x² - 10x + 21 = 0

Answer: x² -10x + 21 = 0
