what is the difference of the two polynomials? (9x² + 8x) - (2x² + 3x)\n7x² + 5x\n7x² + 11x\n11x² + 5x\n11x² + 11x
Answer
Explanation:
Step1: Distribute the negative sign
$(9x^{2}+8x)-(2x^{2}+3x)=9x^{2}+8x - 2x^{2}-3x$
Step2: Combine like - terms
$(9x^{2}-2x^{2})+(8x - 3x)=7x^{2}+5x$
Answer:
A. $7x^{2}+5x$
