You can put this solution on YOUR website!
4x%5E2-10x-14+=+0
= 4x%5E2%2B4x-14x-14+=+0
= 4x%28x%2B1%29-14%28x%2B1%29+=+0
= %28x%2B1%29%284x-14%29+=+0
So, either of the factors is equal to zero. Because anything multiplied by '0' is 0.
If (x+1)=0, then x = -1.
If (4x-14)=0, then 4x = 14. So x = 14%2F4+=+7%2F2+=+3.5
So x = {-1, 3.5} Answer.
