Take 1/2 of the linear coefient (-8) and square it
-8/2=-4, (-4)^2==16
add that to both sides
x²-8x+16+12=16
complete the square
(x-4)²+12=16
minus 12 both sides
(x-4)²=4
sqrt both sides, remember positive and negative roots
x-4=+/-2
add 4
x=4+/-2
x=4+2 or 4-2
x=6 or 2

Tomtit [17]

Answer:

1.8 cycles

Step-by-step explanation:

The average number of clock cycles per instruction is given by the sum of the product of each possible number of cycles by its likelihood.

1 cycle: 50%

2 cycles : 25%

3 cycles : 20%

4 cycles : 5%

Avg = 0.5*1+0.25*2+0.20*3+0.05*4\\Avg= 1.8\ cycles

The average number of clock cycles per instruction is 1.8.
