Question 1039129
.
Use the factors to compute the value of the following


<pre>
1.) {{{25^2-15^2}}} = (25-15)*(25+15) = 10*40 = 400.  <--- Use the formula {{{a^2 - b^2)}}} = (a-b)*(a+b).
</pre>

The rest of examples are on the same pattern. Do them yourself.


<pre>
2.) 62^2-38^2

3.) 97^2-3^2

4.) 150^2-149^2

5.) 1.5^2-0.5^2

6.) 102^2-98^2

7.) 303^2-297^2

8.) 2005^2-2004^2
</pre>

Regarding this formula, &nbsp;{{{a^2 - b^2}}} = {{{(a-b)*(a+b)}}}, &nbsp;see the lesson &nbsp;<A HREF=https://www.algebra.com/algebra/homework/Polynomials-and-rational-expressions/The-difference-of-squares-formula.lesson>The difference of squares formula</A>&nbsp; in this site.
