Step-by-step explanation:
=>x⁴-5x²+4
=>x⁴-x²-4x²+4
=>x²(x²-1)-4(x²-1)
=>(x²-1)(x²-4)
=>(x+1)(x-1)(x+2)(x-2)
hope this helps you.
Its an ellipse.
3 (x+7)^2+2 (y-2)^2-6 = 0
Answer:
4
Step-by-step explanation:
2x+19=x+23
We simplify the equation to the form, which is simple to understand
2x+19=x+23
We move all terms containing x to the left and all other terms to the right.
+2x-1x=+23-19
We simplify the left and right sides of the equation.
+1x=+4
We divide both sides of the equation by 1 to get x.
x=4
Answer:
Step-by-step explanation:
Using the distributive property to expand, we have
Squaring each term, we have
The mistake was that 
not 
Using the fact that the right answer would be
.
Answer:
(-2,7) reflects to (-2,-7)
(3,9) reflects to (3, -9)
(7,2) reflects to (7,-2)
(-3,9) reflects to (-3,-9)
Step-by-step explanation:
in reflection across the x-axis the x value of the coordinate stays the same and the y value is negated to show it been reflected
