Answer:

(a + b)(c + d), ac+ ad+ bc + bd, 2x squared + x - 3 or (2x+ 3)(x -1).

Step-by-step explanation:

For an expression of the form (a + b)(c + d), the expanded version is ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3)(x - 1).

Answer:

x = -2

Step-by-step explanation:

Original equation:

4x + 32 = 24

Subtract 32 from 24

-8

The equation should look like this now:

4x = -8

Divide both sides by 4

x = -2

What are the steps to solve √(0.2)^(−2)? (The answer is 5)

$\bf 0.\underline{2}\implies \cfrac{02}{1\underline{0}}\implies \stackrel{simplified}{\cfrac{1}{5}} \\\\[-0.35em] ~\dotfill\\\\ \left( \sqrt{0.2} \right)^{-2}\implies \left( \sqrt{\cfrac{1}{5}}\right)^{-2}\implies \left( \sqrt{\cfrac{5}{1}}\right)^{+2}\implies \cfrac{(\sqrt{5})^2}{(\sqrt{1})^2}\implies \cfrac{\sqrt{5^2}}{\sqrt{1^2}}\implies 5$
