The sum of −15x2 −5x + 11 and another polynomial expression is −9x2 + 3x −10. what is the other polynomial expression?

Step-by-step explanation:

Let the another expression be P.

Then according to the question,

Open bracket and multiply (-) inside in the bracket, we get

Combining like terms , we get

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
