Question

subtract 3x2 - 8xy - 9y2 from 3x2 - 8xy - 9y2

Answer 1

Answer:

Step-by-step explanation:

Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:-$3x^{2} -8xy-9y^{2}$ from $3x^{2} -8xy-9y^{2} .$  

           To find:-Value of given expression=?

           Solution:-

• We know that subtraction means taking away some value from another value.

1. Subtracting a number from itself.
2. Subtracting 0 from a number.
3. Order property.
4. Subtraction of 1.

       Therefore,

            $(3x^{2} -8xy-9y^{2}) -(3x^{2} -8xy-9y^{2} ) \\=0.$

                  Hence we will get the value $0.$
