​

Answer 1

subtract(-3²+6x+3)from(5x²-9)

Answer is 3x-20

Answer 2

Answer:

$(5 {x}^{2} - 6x - 21) \: is \: the \: answer$

Step-by-step explanation:

$subtract \: (-3²+6x+3) \: from \: (5x²-9)$

Therefore ,

$(5 {x}^{2} - 9) - ( - {3}^{2} + 6x + 3)$

$(5 {x}^{2} - 9) - (9 + 6x + 3)$

$(5 {x}^{2} - 9) - (6x + 12)$

$5 {x}^{2} - 9 - 6x - 12$

$5 {x}^{2} - 6x - 21$
