Step-by-step explanation:

to understand this

you need to know about:

  • algebra
  • PEMDAS

given:

  • A=2x+3
  • B=x²-5x+1

to find:

  • A-5B

let's solve:

[tex] step - 1 : define[/tex]

A-5B=2x+3-5(x²-5x+1)

[tex]step - 2 : solve[/tex]

  1. distribute -5 to the parentheses:2x+3-5x²+25x-5
  2. rewrite:-5x²+2x+25x-5+3
  3. combine like terms:-5x²+27x-2

and

we are done
