Question

What is the difference between the two polynomials (9x^2+8x)-(2x^2+3x)

Answer 1

7x^2 + 5x

Explanation:

(9x^2 + 8x) - (2x^2 + 3x)

multiply the brackets

9x^2 + 8x - 2x^2 - 3x

place the like terms together and then add or subtract them

9x^2 - 2x^2 + 8x - 3x

7x^2 + 5x

Answer 2

`{ \tt{( {9x}^(2) + 8x) - ( {2x}^(2) + 3x)}} \\ = (9 - 2) {x}^(2) + (8 - 3)x \\ = { \bf{ {7x}^(2) + 5x}} \\ \\ { \underline{ \blue{ \tt{becker⚜jnr}}}}`
