Answer:
x is equal to 0.94 and -1.94
Step-by-step explanation:
3x² + 3x + 7 = 0
9x² + 9x + 21 = 0
9x² + 9x + 2.25 = 18.75
(3x + 1.5)² = 18.75
3x + 1.5 = ±√18.75
3x = -1.5 ±√18.75
x = (-1.5 ±√18.75) / 3
x = 0.94, -1.94
One of the ways of dividing polynomials is by synthetic division
The divisor of the synthetic division is x + 5
<h3>How to determine the divisor of the division</h3>
From the question, we understand that:
Entry -5 is on the outside to the left of the shape
The entry represents the zero of the divisor.
Next, we set this entry to the variable (assume the variable is x)
So, we have:

Add 5 to both sides

Hence, the divisor of the synthetic division is x + 5

Absolute Value. The absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.
