1) 
2) 
Step-by-step explanation:
You can factorize the quadratics equations by applying the proccedure shown below:
1) 
Find two number whose sum is 3 and whose product is 2.
These would be 1 and 2.
Rewrite it as folowing:
2) 
Find two number whose sum is 15 and whose product is 50.
These would be 5 and 10.
Therefore, you can rewrite it as folowing:

Hope it helps
Answer:
x = 1
y = -1
Step-by-step explanation:
A*B= (4y-8 3x-3)
1-) (4×2)+(3×y)= 3y+8
2-) (4×x)+(3×(-1))= 4x-3
AB=C
(3y+8 4x-3)=(5 1)
So
3y+8=5 ; y= -3/3 = -1
4x-3=1 ; x=4/4 =1
Answer:
This can be shown as an inequality. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound, and subtract it from the rounded value for the lower bound.
I hope it's helpful!
