<h2>Explanation:</h2>
In this exercise, we have the following equation:
We can write this Quadratic Equation in Standard Form as follows:
So this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:
- The sum is -14
- The product is 24
Those numbers are:
- -12 and -2
- SUM: -12-2 = -14
- PRODUCT: (-12)(-2)=24
So we can write this as:

Answer: G = 50°, I = 50°, H = 80°
Step-by-step explanation:
First and foremos, the sum of three angles of a triangle is 180°
2x + 2x + (4x - 20) = 180°
8x - 20 = 180°
8x = 180° + 20 (adding 20 on both sides)
8x = 200°
x = 200/8
x = 25
The value of the angles can be found by replacing the value of x with 25
2x = 2 x 25 = 50°
Therefore, the angle of two angles are 50°
And the other is (4 x 25) -20 = 80°
4x^2 + 5x - 8 + (- 4x^2 - 5x + 8) = 0
all ur doing is changing the signs so they will cancel each other out.
so ur adding : -4x^2 - 5x + 8
