If 2a^2 +3^1a - 5a^2= 9, then a-a^2=

3.

Explanation:

1) Given expression: 2a² + 3a - 5a² = 9

2) Combine like terms: -3a² + 3a = 9

3) Division property of equalities (divide both sides by 3): - a² + a = 3

4) Rearrange: a - a² = 3

That is the answer requested.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
