The subtraction of b from a is written as a − b. It is basically an algebraic expression and also a binomial. The square of this expression is written as (a − b) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. if a=7 and b=2. then. 2ab = 2 * 7 * 2 = 2 * 14 = 28. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Jul 30, 2020 · (a + b)² = a² + 2ab + b², undoubtedly one of the most famous formulas in mathematics. We were all taught this formula during our childhood. I knew this formula since the age of dinosaurs (4th… (a − b) x + (a + b) y = a 2 − 2ab − b 2 … (1) (a + b) (x + y) = a 2 + b 2 (a + b) x + (a + b) y = a 2 + b 2 … (2) Subtracting equation (2) from (1), we Equations : Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations a-2b/a+2b-2a-b/2a+b so that you understand better Show that the tangent of an angle between the lines x/a+y/b=1 and x/a-y/b=1 is 2ab/a2-b2.
