4x^2-28x+49= 5
First, get the equation equal to zero
4x^2-28x+49-5=5-5
Next, see if you can take a GCF (Greatest Common Factor)
4(x^2-7x+11)=0
We can't factor this, bur we can use the quadratic formula
-b +or- square root (b squared - four (a times c))
7 +or- square root (7^2 - 4(1)(11))
7+or- square root(49-45)
7+or-square root of 5 is your answer!
OOPS!
