We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)
To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c
Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
The answer is 13 minus 3 equals 10


Substitute into

Insert y = 5 into

Answer:
y intercept = (0,-1.2)
x intercept = (3.6,0)
Step-by-step explanation:
For y-int, x=0
3(0)-9(y)=10.8
9y=-10.8
y= -1.2
For x-int, y =0
3x - 9(0)=10.8
3x=10.8
x=3.6
