-(x - 1)(x2 + x + 1)
The discriminant for the quadratic is b2-4ac = 302 - 4*4*45 = 900 - 720 = 180 Since 180 is not a perfect square, the roots of the equation are irrational and it is far from straightforward to solve such an equation by factoring.
15% of 80 = 80*15/100 = 12
It is: 80/250 times 100 = 32%
factoring 80=2*2*2*2*5 115=5*23 LCM=2*2*2*5*23=1,840
When the co-efficient of x2 is 1
Solve by factoring. Solve by taking the square root of both sides.
Solve by factoring.2x2 - 3x + 1 = 0
-(x - 1)(x2 + x + 1)
4 x 12 + 4 x 8 = 4 x (12 + 8) = 4 x 20 = 80
x2-64 = (x-8)(x+8)
X2 - Y2 = (X + Y)(X - Y)

80 times .9
It is: (68/80)*100 = 85%
15% of 80 = 80*15/100 = 12
5x = 80
