Answer:

Step-by-step explanation:

We want to simplify:

$(3a-2b)^2$

Recall the perfect square trinomial pattern:

$(a+b)^2=a^2+2ab+b^2$

Let a = 3a and b = -2b. Thus:

$(3a-2b)^2=(3a)^2+2(3a)(-2b)+(-2b)^2$

Simplify:

$=9a^2-12ab+4b^2$

Our answer is C.

Vihaan finds that the roots of a quadratic equation that contains a difference of squares pattern is x = +-16. What is true abou

tigry1 [53]

The answer to the question, What is true about the graph of the parabola described by the quadratic equation is that the parabola crosses the x-axis at x = ±16.

Since the quadratic equation has roots x = ±16, it implies that its factors are x - 16 and x + 16.

So, the quadratic equation is y = (x - 16)(x + 16) = x² - 16²

Also, we know that the roots of a quadratic equation are the points where the value of the quadratic equation equals zero. At this value, the quadratic equations crosses the x-axis at the roots of the quadratic equation.

Since the roots of our quadratic equation are x = ±16, it implies that the parabola crosses the x-axis at x = ±16.

So, the answer to the question, What is true about the graph of the parabola described by the quadratic equation is that the parabola crosses the x-axis at x = ±16.
