Answer:
(x+4)(2x+1)
Step-by-step explanation:
1. 2x^2+8x+x+4 ----- split the second term in 2x^2 + 9x+4 into two terms.
2. 2x(x+4)+(x+4) ----- Factor out common terms in the first two terms, then in the last two terms.
3.(x+4)(2x+1) ------ factor out the common term x+4
7^2+4^2=x^2
49+16=x^2
65=x^2
x= square root 65

Hello,
If center is (0,0)
x²/a²+y²/b²=1 for a half horizontal axis of a, and a half vertical axis of b
Here
a=2 ==> a²=4
b=8 ==> b²=64
