what is the difference of the two polynomials? (9x^2 + 8x) - (2x^2 + 3x) 7x^2 + 5x 7x^2 + 11x 11x^2 + 5x 11x^2 + 11x
Answer
Answer:
A. $7x^{2}+5x$
Explanation:
Step1: Distribuir el signo negativo
$(9x^{2}+8x)- (2x^{2}+3x)=9x^{2}+8x - 2x^{2}-3x$
Step2: Combinar términos semejantes
$(9x^{2}-2x^{2})+(8x - 3x)=7x^{2}+5x$
