Quadratic Equations ax2 + bx + c = 0 Examples of Quadratic equations 1. x2 +2x – 8 = 0 2. x2 – 10x + 25 = 0 3. 3x2 + x - 2 = 0 Quadratic Formula If [pic] a x2 + b x + c = 0‚ then [pic] Finding the zeros of the quadratic functions - The zeros of a function are the input values which result in an output value of zero. One way of solving quadratic equations is using factoring Examples are the following: 1) x2 + 5x + 6 = 0 Set this equal to zero:

1. What is the exact number of bits in a memory that contains 640M bits? 640 · 1024 = 655‚360 · 1024 = 671‚088‚640 bits. 2. How many bits are in 1 Tb? You are asked to figure out the exact result. Hint: Depending on the tool used to calculate this‚ you may need to use a trick to get the exact result. Note that 220 = 1‚000‚00010 + d‚ where d is the difference between 220 and 1‚000‚00010‚ and that 1T = (1‚000‚00010 + d)2 8 bits/byte => 8 · 1 trillion or 812 => 8‚000‚000‚000‚000 3.

Fiber Intermediates: Fiber Intermediates have large production capacity in India. Globally the demand for all categories of Fiber is increasing at a pace of 3-4 MT annually. Polyester is accounted for 70% of the total growth of fiber in all categories in next decade. This global demand scenario has a positive impact on the Indian market as well. Polyester demand in India is likely to grow at 12% Y-o-Y to .5 MPTA. Demand of Polyester will also result into demand growth of PX which is expected to grow
