Answer:

Addition of 10x^{2} , -5x^{2} ,8x^{2} and -12x^{2} is x^{2}.

Step-by-step explanation:

Given : The terms are 10x^{2} , -5x^{2} ,8x^{2} and -12x^{2}.

To find : The addition of the above terms.

Solution :

  • The given terms are 10x^{2} , -5x^{2} ,8x^{2} and -12x^{2}.
  • We have to find the addition of the above terms.
  • Addition is one of the important arithmetic operation among division, multiplication, addition and subtraction of mathematics.
  • We can find the total of the given quantities with the help of addition.
  • So, the required equation becomes,

      10x^{2} +(-5x^{2} )+8x^{2} +(-12x^{2} )

    = 10x^{2} -5x^{2} +8x^{2} -12x^{2}     [∵ +ve -*(-ve)=-ve]

    = 18x^{2} -17x^{2}

    = x^{2}

  • ∴ Addition of 10x^{2} , -5x^{2} ,8x^{2} and -12x^{2} is x^{2}.
