Question

Factor the expression completely: $7 x squared y plus 28 x y plus 21 y$

7 y (x+1) (x+3)
$7 x + 21$
$14 x + y$
$7 x y$

The correct answer is: 7 y (x+1) (x+3)

$7 x squared y plus 28 x y plus 21 y equals 7 y open parentheses x squared plus 4 x plus 3 close parentheses equals 7 y open parentheses x squared plus 3 x plus x plus 3 close parentheses equals 7 space y left parenthesis x plus 1 right parenthesis left parenthesis x plus 3 right parenthesis$

The quadratic function f(x) = 6.5 x² is the reflection of __________ over the x - axis.
