To simplify the expression, we distribute terms accordingly. It is done as follows:
<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²
Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2.

In order to use the elimination<span> method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top </span>equation<span> by 5. Next add the</span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x</span>
