Subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x.
kicyunya [14]

Simplified value of  subtraction of 7x+27x+2 from -5x^2-2x−5x 2 −2x. is -10x^{2} -38x-2.

Given Expressions  7x+27x+2 and  -5x^2-2x−5x 2 −2x.

Expressions refers to the combination of numbers, variables and symbols. It represents the relationship between variables. They are solved for finding out the value of variables. It is mainly not in equal to form. Subtraction is possible when subtracting the coefficients of same variable.

We have to subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x. and to do this we need to first solve the expressions itself.

7x+27x+2=34x+2------------------1

-5x^{2} -2x-5x^{2} -2x=-10x^{2} -7x-2x--------------------2

Now subtract 1 from 2

=-10x^{2} -7x-2x-34x+2

=-10x^{2} -38x-2.

Hence the simplified value of subtraction is -10x^{2} -38x-2.
