Answer 2

Answer:

Given,

Expression= 7a² -10ab + 3b² .

Final expression= -3a² +5ab+ 6b² .

To Find,

The expression that must be added in our given expression such that the addition gives us the final expression.

Solution,

We can simply find the expression using the property - if a+ b=c.

This means, b= c-a.

In the given case, a is the expression given.

c is the final expression.

b is the expression we need to find.

Substituting the value of a and c.

We get, b=  -3a² +5ab+ 6b² - (7a² -10ab + 3b²) .

b= -10a² +15ab +3b² .

Hence, the expression needed is,  -10a² +15ab +3b² .
