8 авг. 2020 г. · It is basically the formula (a+b)^2=a^2+2ab+b^2 ,but instead of a we have a^2 and instead of b we have b^2. |
13 нояб. 2018 г. · (a + b)^2 is read as "a plus b whole square". Its expansion is given by **(a + b)2 = a2 + 2ab + b2**. |
23 сент. 2014 г. · Expanding (a+b)2 ( a + b ) 2 implies that we are expanding a sum, which in this case is (a+b) ( a + b ) . In other words, we are expanding the ... |
4 апр. 2019 г. · (a－b)²＝(a－b)(a－b)＝a(a－b)－b(a－b)＝a²－ab－ab＋b²＝a²－2ab＋b². But it's still a little…unacceptable. Are there some methods to present it intuitively? |
25 мая 2023 г. · To expand a binomial when the exponent n is greater than 2, we can use the binomial theorem. The binomial theorem provides a formula for expanding a binomial ... |
12 сент. 2021 г. · It depends upon condition. If b is the sole variable; the coefficient is a. If a is the sole variable; the coefficient is (b^2). |
12 июн. 2017 г. · To find the expansion of a2+b2 a 2 + b 2 , let us take the help of Algebraic Identities. (a+b)2=a2+2ab+b2 ( a + b ) 2 = a 2 + 2 a b + b 2 ... |
27 мая 2017 г. · To find the formula of the binomial in the form (a + b)2, we will just multiply (a + b) (a + b). (a + b)^2= (a + b)(a + b). = a^2 + ab + ... |
