WebA 2 - AB + BA - B 2 = A 2 - AB + AB - B 2 = A 2 - B 2 Note : AB = BA is the commutative property of multiplication. Note : - AB + AB equals zero and is therefore eliminated from the expression. Check : 121 is the square of 11 Check : x 2 is the square of x 1 Factorization is : (11 + x) • (11 - x) Equation at the end of step 1 : WebYes, 121 ÷ 11 = 11. 11 x 11 = 121. We can stop checking the factor pairs after 11 as they begin to repeat. So, the factors of 121 are 1, 11, and 121. [Note: If we divide 121 by 12, we get the quotient and remainder as 10 and 1, respectively. So, 12 is not a factor of 121. Similarly, you can check for other numbers as well.]

WebTrigonometry. Factor 121-x^2. 121 − x2 121 - x 2. Rewrite 121 121 as 112 11 2. 112 −x2 11 2 - x 2. Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = 11 a = 11 and b = x b = x. Webx 2 - 121. Furthermore, this is the difference of squares formula we will use to factor x^2-121: a 2 - b 2 = (a + b) • (a − b) As you can see, our problem does not look like the left side of the formula, so first we have to convert our problem to match the left side like so: x 2 - 121 = x 2 - 11 2. Now that it matches, we can simply plug in ... milestones for 10 month baby
