What is the formula of a square B Square?
The (a2 + b2) formula is expressed as a2 + b2 = (a +b)2 -2ab.
What is the formula of x4 y4?
For example, see x4 – y4 as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2).
How do you solve x4 x2y2 y4?
2 Answers
- x4 + x2y2 + y4 = (x4 + 2x2y2 + y4) – x2y2 = (x2 + y2)2 – (xy)2, = [(x2 + y2) + xy] [(x2 + y2) – xy] = (x2 + xy + y2)(x2 –xy + y2) Answered on: 2016/06/03 by ExamFear Guide.
- Given expression is: x4 + x2 y2 + y4 Now, x4 + x2 y2 + y4 = (x4 + 2×2 y2 + y4) – x2 y2 = (x2 + y2)2 – (xy)2
What is the formula of A² B² ²?
⭐So, (a²+b²)²= a⁴+ 2a²b²+ b².
What is the formula for [a + b]^ {4}?
The formula for [a + b]^ {4} is an instance of the binomial theorem which gives the result for [a + b]^ {n} which can be proved true by mathematical induction. This theorem used to be studied in A-level mathematics and can be found on the Internet or in any text on elementary algebra.
What is the value of(a + b) 5?
(a + b) 5 = a 5 + 5a 4b + 10a 3b 2 + 10a 2b 3 + 5ab 4 + b 5. Clearly, doing this by direct multiplication gets quite tedious and can be rather difficult for larger powers or more complicated expressions.
What is the discriminant of b2 – 4ac?
The expression b2 − 4ac b 2 – 4 a c, which is under the √ (sqrt) inside the quadratic formula is called the discriminant. The discriminant is used to determine how many solutions the quadratic equation has. if b2 − 4ac = 0 → 1 solution i f b 2 – 4 a c = 0 → 1 s o l u t i o n
How do you calculate B4+25 in Excel for the web?
In the following example, the parentheses that enclose the first part of the formula force Excel for the web to calculate B4+25 first and then divide the result by the sum of the values in cells D5, E5, and F5.
