Answer:
3x³ + 12x
Step-by-step explanation:
Given
3x(x² + 4) ← multiply each term in the parenthesis by 3x
= 3x³ + 12x
Answer:
x > -1
Step-by-step explanation:
-3x +3 < 6
-3x < 6 - 3 (subtract 3 from both sides)
-3x < 3 (divide both sides by 3)
-x < 1 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by negative numbers)
x > -1 (answer)
Answer:
9pr = 2q^2
Step-by-step explanation:
28.
px^2 + qx + r = 0
If one root is A then the other root is 2A
We have A + 2A = -q/p and A*2A = r/p
So 3A = -q/p so A = -q/3p and A^2 = r/2p so A = √ (r / 2p)
Equating these 2 equations:-
-q/3p = √(r / 2p)
q^2 / 9p^2 = r / 2p
9p^2r = 2pq^2
9pr = 2q^2 (answer)
Answer:
1 + i
Step-by-step explanation:
Given that A is a 3 * 3 singular matrix
one of its eigenvalue ( λ1 ) = 1 - i
Given that the determinant of a singular matrix is = 0
therefore the second eigen value ( λ2 ) = 1 + i
1 - i + 1 + i = 0
