Question

A)5t²+11t²-2t²
B)14k+2p-9k+3p
C)4x³+2x²-5x+2x^4-3x³+3x²+5x+7
D)8y³+y²-6y³+5y-4y²-4y
porfavor podem me ajudar?

Answer 1

A)

= 5t²+11t²-2t²

= 16t² - 2t²

= 14t²

*********************************

B)

= 14k + 2p - 9k + 3p

= 14k - 9k + 2p + 3p

= 5k + 5p

= 5(k + p)

C)

= 4x³ + 2x² - 5x + 2x^4 - 3x³ + 3x² + 5x + 7

= 4x³ - 3x³ + 2x² + 3x² - 5x + 5x + 2x⁴ + 7

= x³ + 5x² + 2x⁴ + 7

= 2x⁴ + x³ + 5x² + 7

D)
= 8y³ + y² - 6y³ + 5y - 4y² - 4y
= 8y³ - 6y³ + y² - 4y² + 5y - 4y
= 2y³ - 3y² + y
