if 3^2 +4x -5 multiplied by 5x, what is the resulting polynomial ?

Sagot :

If it's (5x)(3x² + 4x - 5), here's the solution:

SOLUTION:

(5x)(3x²) + (5x)(4x) + (5x)(-5)

15x³ + 20x² - 25x


ANSWER: 
15x³ + 20x² - 25x



If it's (5x)(3² + 4x - 5), here's the solution:

SOLUTION:

(5x)(3²) + (5x)(4x) + (5x)(-5)

45x + 20x² - 25x

20x² + 20x


ANSWER: 20x² + 20x
