Is 16x^2-56x+49 a perfect square trinomial? How do you know ? If it is, factor the expression. Please show your work

daser333 [38]

Answer:

yes
(4x -7)^2

Step-by-step explanation:

If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.

16x^ = (4x)^2 . . . . a perfect square

49 = 7^2 . . . . . . . a perfect square

-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...

16x^2 -56x +49 = (4x -7)^2

_____

The sign in the binomial factors is the same as the sign of the middle term of the trinomial.

Solve the equation for x.

Advocard [28]

ANSWER

D. x=55

EXPLANATION

The given radical equation is

$\sqrt{x - 6} + 3 = 10$

Add -3 to both sides

$\sqrt{x - 6} = 10 - 3$

$\sqrt{x - 6} =7$

Square both sides.

${ (\sqrt{x - 6})}^{2} = {7}^{2}$

$x - 6 = 49$

Solve for x to get:

$x = 49 + 6 = 55$
