Answer:
x2 +8x +4y +4 = 0
4y= -x2 -8x -4y = -.25*x^2 -2x -1
a = -.25b = -2c = -1
x position of vertex:
h = -b / 2a
h = 2 / 2*-.25h = 2 / -.5h = -4
y position of vertex:
k = ah^2 + bh + ck = -.25*-4^2 + -2*-4 + -1k = -4 +8 -1k = 3
VERTEX = (-4, 3)*
x value of focus =x value of vertex = -4
y value of focus =(1 (-b^2 -4ac)) / 4a
a = -.25 b = -2 c =-1
y value = (1 (-4 -4*-.25*-1)) / 4*-.25
y value = (1 (-4 -4*-.25*-1)) / -1
y value = (1 -4 +1) / -1y value = (-2 / -1)y value = 2
focus value = (-4, 2)
Answer is the last one.
Answer: 56
Step-by-step explanation:
<h3>I'll teach you how to distribute −2x(−10x+1)</h3>
----------------------------------------------------
−2x(−10x+1)
Apply the distributive law:
Ex. of distributive law:
a(b+c)= ab+ac
-2x(-10x)+(-2x)*1
Apply minus/plus rule:
2*10xx-2*1*x
Simplify 2*10xx-2*1*x:
2*10xx= 20x^2
2*1*x= 2x
20x^2-2x
Your Answer Is 20x^2-2x
plz mark me as brainliest if this helped :)
