What is the A B 2 formula?
The (a + b)2 formula is the algebraic identity used to find the square of the sum of two numbers. To find the formula of the binomial in the form (a + b)2, we will just multiply (a + b) (a + b).
What is the angle between two vectors if they are parallel?
Two vectors are parallel ( i.e. if angle between two vectors is 0 or 180 ) to each other if and only if a x b = 1 as cross product is the sine of angle between two vectors a and b and sine ( 0 ) = 0 or sine (180) = 0.
What is the formula of a B a B?
We will find this product using the formula: (a-b)(a+b)=a2- b2 Here a=300 and b=3. Then we get: (300-3) × (300+3) =3002 – 32 = 90000-9 = 89991. Therefore, 297 × 303 = 89991. Example 3: Find the roots of the quadratic equation x2+5x+6=0 using algebra formulas for quadratic equations.
How do you find (a-B) from a+B and AB?
So just put values of A+b and ab, you can find (A-B) like this, and then add the equations (A+B) (A-B) which is equal to 2 ab If ab = 48 and a+b = 2, then what is a and b?
How to find the value of A and B from two equations?
First, if we assume that a and b are real numbers, then they must have the same sign and be non-zero for ab to be positive, from the first equation. However, a closer look at the second equation, a + b = 2, tells us that we cannot get any values of a and b for the constraints given by both equations.
What is 4b/a if a/b = 2?
By normal division, you’ll get 2 as the answer. If a/b = 2, then 4b/a=2!!!! Hope this helps!! If playback doesn’t begin shortly, try restarting your device. This video is unavailable. An error occurred while retrieving sharing information. Please try again later.
Are A and B complex numbers?
However, a closer look at the second equation, a + b = 2, tells us that we cannot get any values of a and b for the constraints given by both equations. Hence, a and b are complex numbers. Since their sums are real (from the second equ All the answers already given are correct solutions to the problem.
