Use a special-product rule to factor the perfect-square trinomial.<br> 81y^2+ 126y + 49
Ivahew [28]

Answer:

The perfect -square trinomial

                  (9y+7)²

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given polynomial equation

                        81 y² + 126 y +49

               ⇒     9² y² + 2(9)(7)y + 7²

                ⇒   (9y)² + 2(9)(7)y +7²

we will use formula

   (a+b)² = a² + 2ab +b²

             ⇒ (9y+7)²

<u><em>Final answer:-</em></u>

The perfect -square trinomial

                  (9y+7)²

What is the range of the function f(x) = 3x2 + 6x – 8?
umka2103 [35]

Answer: C... {y|y ≥ -1}

Step-by-step explanation:

f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.

in vertex form (h, k) = (-1, -11)

This meaning the range ={y|y ≥ -11}
