Set the equation equal to zero.
3x2 - x = -1
3x2 - x + 1 = 0
The equation is quadratic, but can not be factored. Use the quadratic equation.
5x - 16 = 3x2x - 16 = 02x = 16x = 8
the answer is 6
x = 1/3
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
First you put -6 under 6 so they cancel each other out. The do 7 - 6 which equals 1. So x equals 1
5x - 16 = 3x2x - 16 = 02x = 16x = 8
2sinx+1 equals 0
1
-(4-3) -(1) -1
a+a=1 2a=1 a=1/2
3*2*4 = 24
x=1
1
the answer is 6
2x+10=9+11-3x2x+10=20-3x5x+10=205x=10x=2
y = -6
x = 1/3
