You can put this solution on YOUR website! 49x^2+56x+16
Can this equation be factored or is it prime
:
Not only can it be factored, it is a perfect square! Look at the coefficient of x^2 and the 3rd term, both are squares. Write the factors and see what you have:
:
(7x + 4)(7x + 4), FOIL this: 49x^2 + 28x + 28x + 16
