Step-by-step explanation:
Use difference of squares:
Answer:
in x>5 x is larger than 5
Step-by-step explanation:
x=5 means x is equal to 5
x>5 means x is greater than 5
The Approximate the solution to the equation using three iterations of successive approximation is option b: 27/8.
<h3>What is the
iterations about?</h3>
In the equation given:
Note that:
x²-3x+2 = square root √x-2 + 2
Therefore:
x⁴-6x³+9x²= square root x-2
x² = 3.375
Convert 3.35 into fractions and will get 27/8. So, The Approximate the solution to the equation using three iterations of successive approximation is option b: 27/8.

Answer:
When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.
For example:
(x - y)² = x² − 2xy + y²
(x - y)³ = x³ − 3x²y + 3xy² − y³
(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴
etc.
Answer:
26 or 62
Step-by-step explanation:
If one of the two digits of a two-digit number is three times the other digit, then the options for the two-digit number are:
If you interchange the digits of this two-digit number and add the resulting number to the original number, you get 88.
From inspection of the listed pairs of numbers, the only pair that sums to 88 is 26 and 62:
⇒ 26 + 62 = 88
Therefore, the original number is either 26 or 62.
