Question

from the quadratic equation from the roots given -3 & -7​

Answer 1

Answer:

x

$x^2 + 10x + 21$

is the given equation

Answer 2

Step-by-step explanation:

the question should be form the quadratic equation

then the the answer will be as follows

x = -3 ; x = -7

x+3=0 and x+7=0

0 x 0 = 0 so 0 = ( x+3 ) ( x+7 )

x² + 3x + 7x + 21 = 0

x² + 10x + 21 = 0 ( this the equation formed )
