Answer:
x = −4 and x = 4
Step-by-step explanation:
4x² = 64
Lets get x² on its own. To do this we divide each sides by 4:
x² = 16
Now to get just x, we need to square root this answer:
√x² = √16
x = √16
x = 4
But this can be ±4 as it -4 and 4 squared both give 16.
So your answer is x = −4 and x = 4

When you have a polynomial function, and you need to graph it, you need to find- y intercept (the constant at the end) zeroes( factor equation and set factorsequal to zero) end behavior( if the highest exponent is even, then if the leading coefficient is positive both sides continue up, if the leading coefficient is negative both sides continue down. If the highest exponent is odd, then if the leading coefficient is positive left side continues down, right side continues up, if the leading coefficient is negative then visa versa.) and multiplicity( if the same factor occurs multiple times- if it occurs an odd number of times, then the graph passes the x axis, if it occurs an even number, then it merely touches).
Hope I helped!
