Find each product with work (3g + 2)(3g–2)​
Amiraneli [1.4K]

Answer:

See explanation!

Step-by-step explanation:

<u>Due to the way the question is expressed we will assume that it means to find the product of this expression (thus simplify or factor our the equation). </u>

So let us solve as following:

(3g+2)(3g-2)=0\\\\(3g)(3g)+(3g)(-2)+(2)(3g)+(2)(-2)=0\\\\9g^2-6g+6g-4=0\\\\9g^2-4=0\\9g^2=4\\\\g^2=\frac{4}{9}\\ \\g=(+/-)\sqrt{\frac{4}{9} } \\\\g=(+/-)\frac{2}{3}

So we have factored our the expression and solve for the values of g which since its <em>squared, </em>the solution can be either positive or negative. Thus

g=\frac{2}{3}\\ and g=-\frac{2}{3}
