Which equation is true?

amid [387]

Answer:

$(3x-5)(3x+5)$

Step-by-step explanation:

Difference of squares states that:

$a^2-b^2=(a-b)(a+b)$

In this case...

$a^2=9x^2\\\sqrt{a^2}=\sqrt{9x^2}\ (take\ the\ square\ root\ of\ both\ sides)\\a=3x$

$b^2=25\\\sqrt{b^2}=\sqrt{25}\ (take\ the\ square\ root\ of\ both\ sides)\\b=5$

This means that...

$9x^2-25=(3x-5)(3x+5)$
