Question

Tolong bantuannya ya! :)
sederhanakan :
(3akar2-4akar3)(akar2+akar3)
tentukan penyelesaian dari:
3x-2/5=4-1/2x

Answer 1

1. (3√(2) - 4√(3)) * (√(2) + √(3))
3.2 + 3√(6) - 4√(6) - 4.3
6-12-√(6 ) = -6 - √(6) =
- (6+√(6))
2. (3x-2)/5 = (4-1)/2x
2x(3x-2) = 5.3
6x^2 -4x = 15
0 = 6x^2 -4x -15
a=6
b=-4
c= -15
-b±√(b^2 - 4ac)/2a
4±√(16- 4.6.-15)/12
4±√(16+360)/12
4±√(376)/12 = 4±2√(94)/12
x1 = (2+√(94))/6
x2 = (2-√(94))/6
