Answer:
4y - y^2 = 10
Step-by-step explanation:
Let x and y be the two numbers
x+y = 4
xy = 10
Taking the first equation and solving for x
x = 4-y
Substituting this into the second equation
(4-y) *y = 10
4y - y^2 = 10
Hey there!!
Okay here is how you solve this... first you look for factors of 12 and 35... for example...
12m² - m - 35
<u>(4m - 7)(3m + 5)</u><u /> <---- This is the factored form!<u>
</u>m = 7/4 and -5/3
<u />
I hope this helps! ^__^
