Question

What should be subtracted from
$9x {}^{2} y {}^{2} - 7y {3}^{} + 12y {}^{2} to \: get \: - 14y {}^{2}$

​

Answer 1

Step-by-step explanation:

subtrahend= minuend - difference

so required expression=

$= 9 {x}^{2} {y}^{2} - 7 {y}^{3 } + 12 {y}^{2} - ( - 14 {y}^{2})$

$= 9 {x}^{2} {y}^{2} - 7 {y}^{3} + 26 {y}^{2}$
