Please help me solve these two problems. My addition sign is not working on my keyboard.
a^4b plus a^2b^3
18z plus 45plus z^2
I assume you want to factor the expressions?
a^4b + a^2b^3 = a^2b(a^2+b^2)
z^2 + 18z + 45 = (z+3)(z+15)
Thank you Steve and can you please explain how you got both answers, so that I can get a better understanding. Thanks
I'm sorry to hear that your addition sign is not working on your keyboard. However, I can still help you solve the problems using alternative methods.
For the first problem, a^4b plus a^2b^3, we can factor out the common terms to simplify the expression. The common term here is "ab", so we can write it as:
ab(a^4 + a^2b^2)
Now, we have factored out the common term and simplified the expression.
For the second problem, 18z plus 45 plus z^2, we can combine like terms to simplify the expression. The like terms here are the terms with "z" in them, so we can combine them as follows:
18z + z^2 + 45
There isn't any common factor that can be factored out further, so we have simplified the expression by combining like terms.
I hope this helps! Let me know if you have any further questions.
