Answer:
Step-by-step explanation:
![Remember:\\(a+b)(a-b)=a^2-b^2\\\\(6+5i)(6-5i)=6^2-(5i)^2=36-(-1)*25=36+25=61\\](https://tex.z-dn.net/?f=Remember%3A%5C%5C%28a%2Bb%29%28a-b%29%3Da%5E2-b%5E2%5C%5C%5C%5C%286%2B5i%29%286-5i%29%3D6%5E2-%285i%29%5E2%3D36-%28-1%29%2A25%3D36%2B25%3D61%5C%5C)
Answer:
Multiply each term in the first expression by each term in the second expression and combine like terms.
24a3+8a2+6a+4
Step-by-step explanation:
To find the x-int., let y = 0 and solve for x: 13x = 6, so x = 6/13: (6/13, 0)
To find the y-int., let x =0 and read off the y-int: (0, -6)
Here is the answer
4(2a+3b)(2a-3b)
<u>0.8 / 9.2 = x + 0.2</u>
Perform the division on the left side: 0.08696 = x + 0.2
Subtract 0.2 from each side: <em>-0.113 = x</em> (rounded)
