We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
Y=-8/2x+5

Answer:
20 cups
Step-by-step explanation:
Michelle: 10 3/5 cups made
Leslie: 9 2/5 cups made
<u>Steps:</u>
<em>First, let's turn each number into decimal form.</em>
10 3/5 = 10.6
9 2/5 = 9.4
<em>Then, add</em>
9.4 + 10.6 = 20
<em>Conclusion</em>
They made 20 cups in all
Note:
Hope this helped :)
Have a nice day
