    D. If she factored out a -7, then the expression in parentheses would be (x + 12), matching the first parentheses.

    can the polynomial below be factored into a perfect square ? if not select the answer that best describes why not 49x^2-70x+25 A. The x^2 coefficient does not permit the factoring B. The x^2 coefficient does permit the factoring, but the x coefficient does not permit the factoring. C. The constant value does not permit the factoring. D. The polynomial may be factored into a perfect square.

    That's a perfect square. (7x-5) is multiplied by itself
