Answer:
x = 3i
Step-by-step explanation:
(x+5)² - 4 = 12
simplify (x+5)²
x × x + 5 × 5 - 4 = 12
x² + 25 - 4 = 12
x² + 21 = 12
combine the like terms
x² = 12 - 21
x² = -9
square root both sides to solve for x
√x² = √-9
the square cancels the square root, so we have
x = √-9
x = 3i
Answer:
A.all variables are raised to an even power.
B. there are only two terms.
Step-by-step explanation:
An example of an expression that is a difference of two squares is:
= a² - b²
In this case;
Where both terms have an even power and there are only two terms.
Given ---›
y = -3
&
y = x - 0.8
So,
=> x = y + 0.8
=> x = -3 + 0.8
=> x = -2.2
Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)
