6 x^2+5 x-6
Factor the quadratic 6 x^2+5 x-6. The coefficient of x^2 is 6 and the constant term is -6. The product of 6 and -6 is -36. The factors of -36 which sum to 5 are -4 and 9. So 6 x^2+5 x-6 = 6 x^2+9 x-4 x-6 = 3 (3 x-2)+2 x (3 x-2):
3 (3 x-2)+2 x (3 x-2)
Factor 3 x-2 from 3 (3 x-2)+2 x (3 x-2):

Answer:
$3.4
Step-by-step explanation:
Total amount spent by Mila equals $71.05
She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05
Amount spent on thread = $71.05 - Amount spent on fabrics.
Amount spent on thread = $71.05 - $64.25 = $6.8
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
