Pls help 4 pointz
the question is below

Step-by-step explanation:

Simplifying

4x2 + -20 = 556

Reorder the terms:

-20 + 4x2 = 556

Solving

-20 + 4x2 = 556

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation.

-20 + 20 + 4x2 = 556 + 20

Combine like terms: -20 + 20 = 0

0 + 4x2 = 556 + 20

4x2 = 556 + 20

Combine like terms: 556 + 20 = 576

4x2 = 576

Divide each side by '4'.

x2 = 144

Simplifying

x2 = 144

Take the square root of each side:

x = {-12, 12}

Here are all the steps, and what they do:

STEP 1: HORIZONTAL TRANSLATION

We transform

The general transformation is

These transformations translate the graph horizontally, k units to the left if k>0, k units to the right if k<0.

In this case, k = -1, so we translate the original graph 1 unit to the right.

STEP 2: VERTICAL STRETCH

We transform

The general transformation is

These transformations stretch the graph vertically. The graph expands if |k|>1, while it shrinks if 0<|k|<1. If k is negative, we also reflect the graph with respect to the x axis.

In this case, k = 3, so we stretch the graph vertically by a factor 3.

STEP 3: VERTICAL TRANSLATION

We transform

The general transformation is

These transformations translate the graph vertically, k units up if k>0, k units down if k<0.

In this case, k = 4, so we translate the graph 4 units up.

So, we start from the original graph of and we:

(the order is important!)

to get the graph of
