Factor Completely<br><br> 2x²-4x+6
vagabundo [1.1K]


okay well usually what I would tell you would be to use the ABC method. you would multiply A (2) by C (6) to get twelve. so you need two numbers that multiply to twelve and add to -4 (the B value). but there are no numbers that fit this description so you have to use the GCF method instead

for this method you must find the GCF for all three numbers which in this case is 2.        2(x^2-2x+3) all these numbers are now prime so this is the factored form
