-2x^2 + x + 4x^2 + 5x + 1 + 3=2*x^2+6x+4=2(x^2+3x+2)=
2*( x^2+x+ 2x+2)= 2*( x(x+1)+ 2(x+1) )=2*(x+1)(x+2)

-2x^2 + x + 4x^2 + 5x + 1 + 3
group like terms
-2x^2 + 4x^2 + x + 5x + 1 + 3
add like terms
2x^2 + 6x + 4
factor 2 out
2(x^2 + 3x +2)
factor completely (in case your teacher told you to do this or something)
2(x + 1)(x + 2)

I will first start off by combining all alike terms
={-2x^2+4x^2} +{5x+x} +{1+3}
=2x^2+6x+4
you can continue reduce it if u choose
=2(x^2+3x+2)

I put in at http://www.algebrahelp.com/ and got this.
Simplifying
-2x2 + x + 4x2 + 5x + 1 + 3 = 0
Reorder the terms:
1 + 3 + x + 5x + -2x2 + 4x2 = 0
Combine like terms: 1 + 3 = 4
4 + x + 5x + -2x2 + 4x2 = 0
Combine like terms: x + 5x = 6x
4 + 6x + -2x2 + 4x2 = 0
Combine like terms: -2x2 + 4x2 = 2x2
4 + 6x + 2x2 = 0
Solving
4 + 6x + 2x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '2'.
2(2 + 3x + x2) = 0
Factor a trinomial.
2((2 + x)(1 + x)) = 0
Ignore the factor 2.
Subproblem 1Set the factor '(2 + x)' equal to zero and attempt to solve:
Simplifying
2 + x = 0
Solving
2 + x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + x = 0 + -2
Combine like terms: 2 + -2 = 0
0 + x = 0 + -2
x = 0 + -2
Combine like terms: 0 + -2 = -2
x = -2
Simplifying
x = -2
Subproblem 2Set the factor '(1 + x)' equal to zero and attempt to solve:
Simplifying
1 + x = 0
Solving
1 + x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + x = 0 + -1
Combine like terms: 1 + -1 = 0
0 + x = 0 + -1
x = 0 + -1
Combine like terms: 0 + -1 = -1
x = -1
Simplifying
x = -1Solutionx = {-2, -1}

-2x^2+x+4x^2+5x+1+3=0
-2x^2+4x^2+x+5x+1+3=0
2x^2+6x+4=0
there fore (2x+2) (x+2)=0
