Step-by-step explanation:
Sean has 10 pounds of birdseed, which he separates into smaller bags. The line plot shows the weights of 8 bags Sean made. Sean's Bags of Birdseed x XXXXCO - 2 1 3 1 5 8 Weight (pounds) 3 4 1 co How many pounds of birdseed does Sean have left after making the bags? Move numbers to the boxes to show the answer. If there is no whole number, put a 0 in the first box.
I'm pretty sure you are looking for factored forms as an equivalent equation, so here is how you do it.
This equation would be solved by difference of squares. 16, x^4, and 81 are all perfect squares ( which means that it is a number multiplied by itself, 16 is 4 x4 for example). So the first thing you want to do is recall the formula which is
(a^2 - b^2) = (a - b)*(a + b)
(16x^4 - 81)= 0
Find the sq. root of 16 which is 4, and of x^4 which is x^2, and 81 which is 9. Now re write it in the (a - b)*(a + b) format. ----> (4x^2 - 9)*(4x^2 + 9) = 0
