Answer:
(x - 4)(x + 4)(x - 1)(x + 1)
Step-by-step explanation:
Given
- 17x² + 16
Use the substitution u = x², then
u² - 17u + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the u- term (- 17)
The factors are - 16 and - 1, then
u² - 17u + 16
= (u - 16)(u - 1) ← replace u by x²
= (x² - 16)(x² - 1) ← both factors are difference of squares
= (x - 4)(x + 4)(x - 1)(x + 1)
You did
D=(x2-x1)²+(y2-y1)²
it should be
D=
and BC, you did (-4)²=-16, it should be equal to 4
if you do the math which is evaluate
A=(5,3)
B=(1,5)
C=(3,0)
AB=
BC=
CA=
add them to get total
D=(x2-x1)²+(y2-y1)²
