Answer:
x = 4 or x = 1 or x = -2 or x = -3/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^4 - 3 x^3 - 21 x^2 - 2 x + 24 = 0
The left hand side factors into a product with four terms:
(x - 4) (x - 1) (x + 2) (2 x + 3) = 0
Split into four equations:
x - 4 = 0 or x - 1 = 0 or x + 2 = 0 or 2 x + 3 = 0
Add 4 to both sides:
x = 4 or x - 1 = 0 or x + 2 = 0 or 2 x + 3 = 0
Add 1 to both sides:
x = 4 or x = 1 or x + 2 = 0 or 2 x + 3 = 0
Subtract 2 from both sides:
x = 4 or x = 1 or x = -2 or 2 x + 3 = 0
Subtract 3 from both sides:
x = 4 or x = 1 or x = -2 or 2 x = -3
Divide both sides by 2:
Answer: x = 4 or x = 1 or x = -2 or x = -3/2
Answer:
19/20
Step-by-step explanation:
write all numerators above the common denominator 20
14+5/20
19/20
Equation - x = -3/10 + (10－1）
The original number is 9.3 because
x = -3/10 + (10－1）
x = -3/10 + 9
x = 9.3
Even
means ends with 0,2,4,6,8
adds to 10
the last number cannot be 0 because the first cannot be add to 10
it can be
8xx2
6xx4
4xx6
8xx2
where x is any whole number you want
