Question

Choose the correct simpilfication of (7x^3-8x-5)+(3x^3+7x+1)

Answer 1

Answer:

$10x^{3} -x-4$

Step-by-step explanation:

$(7x^3-8x-5)+(3x^3+7x+1)$

$7x^3+-8x+-5+3x^3+7x+1$

$(7x^{3} +3x^{3} )+(-8x+7x)+(-5+1)$

$10x^{3} -x+-4$

Answer 2

Answer:

Step-by-step explanation:

(7x³-8x-5)+(3x³+7x+1) =7x³ - 8x - 5 + 3x³ + 7x + 1

Combine the like terms

      = 7x³ + 3x³ - 8x + 7x - 5 + 1

Now, add/ subtract the like terms

     = 10x³ - x - 4
