Answer:
x^4 - 11·x^2 + 18 = 0
I use Vieta's formulas
-9·(-2) = 18 and -9 + (-2) = -11
(x^2 - 9)·(x^2 - 2) = 0
(x + 3)·(x - 3)·(x + √2)·(x - √2) = 0
Answer:
£45
Step-by-step explanation:
Given data
P= £300
R=5%
T= 3 years
SI= PRT/100
substitute
SI= 300*5*3/100
SI=4500/100
SI= £45
Hence the interest is £45
Solve your equation step-by-step.
2(x−3)−17=13−3(x+2)
Simplify both sides of the equation.
2(x−3)−17=13−3(x+2)
Simplify
2x−23=−3x+7
Add 3x to both sides.
2x−23+3x=−3x+7+3x
5x−23=7
Add 23 to both sides.
5x−23+23=7+23
5x=30
Divide both sides by 5.
5x/5 = 30/5
x=6
