Answer 2

Answer:

Jayanti had rupees :-

${12x}^{2} + x + 2$

Jayanti spent rupees :-

${4x}^{2} - 5x - 9$

To find out how much money left. We have to subtract both numbers.

${12x}^{2} + x + 2 - ( 4 {x}^{2} - 5x - 9)$

${12x}^{2} + x + 2 - {4x}^{2} + 5x + 9$

${12x}^{2} - {4x}^{2} + x + 5x + 2 + 9$

${8x}^{2} + 6x + 11$
