Let's try to simplify x^2 + 16. It's a sum of two squares:
x^2 + 16 = 0
x^2 = -16
The problem is, we can't take a square root of a negative. This is where imaginary numbers come in.
Remember that square roots have a plus or minus symbol outside:
±√-16 = ±4i
Our two roots are 4i and -4i. Therefore, the trinomial simplifies to:
(x + 4i)(x - 4i)
If we attempt to divide x + 4 by these two binomials, we will find that 4 and 4i are not like terms. Therefore, we can't simplify this expression.
Since the values are the same on both sides the matrix value is a=1
1.) Factor 9u^2-12u
2.) Cancel any common factors (in bold will be the terms eliminated)
Final answer is:
3u-4
Therefore, the answer is
C. 3u-4
700 (seven hundred), 43,000,000 (forty-three million), 554 (five hundred and fifty-four)
hope this helps
