Answer:
3-2x+1
Step-by-step explanation:
If we indicate x the generic number we can write this expression
3-2x+1
when a sign of an operation is not expressed it means that the operation is multiplication
2x means 2*x
Take out the GCF
5(2x^2+3x-14)
Use slip and slide for the inner trinomial
x^2+3x-28
(x+7)(x-4)
(x+7/2)(x-4/2)
(2x+7)(x-2)
Final answer: 5(2x+7)(x-2)
