Answer 1

your answer is x = -1 and x = 3 !!

step 1.) write -2x as a difference

step 2.) factor out x from the expression

step 3.) factor out -3 from the expression

step 4.) factor out x + 1

step 5.) when the product of factors equals 0, at least one factor is 0

step 6.) solve the equation for x

hence your answer would be x = -1 and x = 3 !!
