Answer:
b) f (-1) ese es el resultado
Answer:
a = 4
Step-by-step explanation:
first, you are supposed to subtract both sides by 6 so you will get:
<u>6 - 4a = -10</u>
-6 -6
-4a = -16
Then, you divide both sides by -4 to cancel out the -4 before the "a"
<u>-4a</u> = <u>-16</u>
-4 -4
Last, you will get a = 4 and that is your answer because when you divide a negative number by another negative number, you will get a positive number.
Put it in the form
ax^2 + bx + c = 0
use the quadratic formula
x = [ -b + sqrt( b^2 - 4 ac ) ] / 2a
x = [ -b - sqrt( b^2 - 4 ac ) ] / 2a
7v^2 - 7v - 22 = 0
a = 7
b = -7
c = -22
v = [ 7 + sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = 2.34
v = [ 7 - sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = -1.34
