WebExpand the brackets \ ( (y + 2) (y + 3)\). Multiply the first items in the brackets: \ (y \times y = y^2\) Multiply the terms that are on the outsides of the brackets: \ (y \times 3 = 3y\)... WebThe longer way to do it would be to write (a+5)^2 as (a+5) (a+5) and multiply out that way. However, there is a shorter way where all you have to do is square the first term, square the last term and multiply their product by 2. Therefore, (a+5)^2= a^2 + 10a + 25.

WebI make the last 2 brackets expanded (3 + 4X + X^2) Is my approach correct? Jake2954 Give the answer as the square root of a polynomial Let [latex]\mathrm {f} (x) = (2-x) (3+x)^ {0.5} (1+x)^ {0.5}[/latex]. Then [latex](\mathrm {f} (x))^2 = (2-x)^2 (3+x) (1+x)=x^4-9x^2+4x+12[/latex] So [latex]\mathrm {f} (x)= (x^4-9x^2+4x+12)^ {0.5}[/latex]. WebExpand what is in $[\cdots]$ first, and then combine with the $\lor (D\land B\land F)$ term. Technically speaking, $\lor$ is a binary operator, which means it takes two inputs, so the expression needs some kind of grouping symbols.
