Answer 1

Answer:

The product of 5x + 3 and 8x2 - 2x + 5 is 3x2 and 8 + 3x + 5

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((5x +  (3and8 • x2)) -  2x) +  5

Step  2  :

Trying to factor a multi variable polynomial :

2.1    Factoring    3x2and8 + 3x + 5

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :

Answer 2

Answer:

40X^3 - 34X^2 + 4X + 15

Step-by-step explanation:

Using Algebraic expansion, the first number in bracket with its coefficience multiplies the second bracket. Equally , the second number in the first bracket is also used to multiply the second bracket, taking note of the sign (addition and minus sign)

5x(8x^2 -2x +5) +3 (8x^2 -2x +5)

= 40X3 - 10X^2 + 10X -24X^2 - 6X + 15

= 40X^3 - 34X^2 + 4X + 15
