Help me please .
solve this following equation
:)

Step-by-step explanation:

i solve (a)

put x=2

3(2)³-4(2)²-5(2)+2=3(8)-16-10+2=24-26+2=0

so x=2 is one solution.

divide by 2 synthetically

2 |3   -4   -5   2

  |      6    4   -2

 |

   3   2    -1  |0

3x²+2x-1=0

3x²+3x-x-1=0

3x(x+1)-1(x+1)=0

(x+1)(3x-1)=0

x=-1,1/3

so solutions are -1,1/3,2

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
