Question

Obtain the quadratic equation if roots are -3, -7.​

Answer 1

Step-by-step explanation:

$= > {x}^{2} + 10x + 21 =0$

Answer 2

Answer:

x^2 + 10 x + 21 = 0

Step-by-step explanation:

Factors = (x-(-3)) and (x-(-7))

=> (x+3)(x+7)

=> x^2 + 10 x + 21

Since it's an equation and not a polynomial, it is equal to zero

x^2 + 10 x + 21 = 0
