Finding the Difference (8x2+3x19)(7x214)(8x^2 + 3x - 19) - (7x^2 - 14)

Find the difference of the polynomials:

(8x2+3x19)(7x214)(8x^2 + 3x - 19) - (7x^2 - 14)

First, distribute the subtraction by multiplying each term in the second polynomial by 1-1, which changes their signs:

8x2+3x197x2+148x^2 + 3x - 19 - 7x^2 + 14

Next, rearrange the terms to group the like terms together:

8x27x2+3x19+148x^2 - 7x^2 + 3x - 19 + 14

Finally, combine the like terms by adding their coefficients:

x2+3x5x^2 + 3x - 5
