Answer:
1) (x-2)(x-5)
2) (6r-5)(r+4)
Step-by-step explanation:
1)
It will just be x since the coefficient is 1
To figure out the second number you need to think of the multiples of 10.
So either 2 and 5 or 1 and 10. Since 2 and 5 add to 7 it's them.
They're negative since 7 is and can still make a positive 10.
2)
This one is more just plugging and guessing to see which on works.
Find the multiples of both 6 and 20, afterwards plug in the multiples til you get 19 in the final product.
Since 20 was negative the one of the numbers would be negative.
I can't explain it lol
