Answer:

10x + 1

Solution:

(4x2 + 5x) + (x2 - 5x + 1)

Multiply the monomials

(8x + 5x) + (2x - 5x + 1)

Remove the parenthesis

8x + 5x + 2x - 5x + 1

Reorder the like terms

(8x + 5x + 2x - 5x) + 1

Collect like terms by adding their coefficients

(8 + 5 + 2 - 5) • x + 1

Calculate

10x + 1

Hope that helps you :)

S olution:

(4x2 + 5x) + (x2 - 5x + 1)

= 4x2 + 5x + x2 - 5x + 1

= 4x2 + x2+ 5x - 5x + 1

= 5x2 + 0 + 1

= 5x2 + 1
