in the problem 2(a-2), you distribute the 2 to everything within the grouping symbols, giving you 2a-4 as your final evaluated answer. if they wanted you to solve, you set it to zero as such
2a-4=0
2a=4
a=2
Answer:
8x² + 6x - 35
Step-by-step explanation:
A = (2x + 5)(4x - 7)
Front: 2x * 4x = <em>8x²</em>
Outside: 2x * (-7) = <em>-14x</em>
Inside: 5 * 4x = <em>20x</em>
Last: 5 * -7 = <em>-35</em>
Add up: <em>8x² - 14x + 20x -35</em>
Simplify: 8x² + 6x - 35
