X^2+3×-7=5x-8
X^2-2x+1=0
(X-1)(x-1)=0
X=1 x=1
Y=1^2+3*1-7
Y=1+3-7
Y=4-7
Y=-3
×=1 y=-3
Solution = (1,-3)
Answer= one solution

Answer:
Step-by-step explanation:
Given:
Required
Multiply
The above can be written as
Split the above expression
Collect like terms
Apply first law on indices
Hence, is equivalent to
You FOIL (First, Outer, Inner, Last)
If you FOIL, you should get 2y^2 - 4y + 4y^2 - 8y +12y -24
The answer to the problem is A
