simplify (3xsquared+2x-5)+(5xsquared-4x+6)

Question

a. -2xsquared +6x-11

b. 8xpower of 4+2xsquared-1

c. 8xsquared+2x-1

d. 8xsquared-2x+1

Answer 1

     (3x² + 2x - 5) + (5x² - 4x + 6)

Here you have two trinomials being added to one another. To simplify this expression, simply combine like terms:

     (3x² + 5x²) + (2x - 4x) +  (-5 + 6)

          (8x²)     +   (-2x)    +     (1)    

         ==>     8x² - 2x + 1
