Question

what is the difference of the two polynomials?$(9x^{2}+8x)-(2x^{2}+3x)LXB07x^{2}+11xLXB17x^{2}+5x$

Explanation:

Step1: Distribute the negative sign

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

Step2: Combine like $x^2$ terms

$9x^2 - 2x^2 = 7x^2$

Step3: Combine like $x$ terms

$8x - 3x = 5x$

Step4: Combine the results

$7x^2 + 5x$

Answer:

$7x^2 + 5x$ (the fourth option)
