Answer: (y-5)(y+3)
<em>// If the coefficient of the y^2 is 1 and equation has integer-solution, than 15 must be divisible to that solution. Fermat's Theorem consequence</em>
It's obvious that y=5 is solution.
<em>// If x1 and x2 are solution to quadratic equation, ay^2+bx+c, where a is 1, then x1*x2=c. Fermat's Theorem</em>
Divide equation by (y-5), If you cannot do this look for other obvious solutions.
No, they are not equivalent
-41/2 would be division because the fraction would indicate that. you would be dividing -41 by 2. this would get you -20 1/2.
(-4)1/2 would be multiplying because of the parentheses. you would be doing -4 x 1/2 and that would get you -2.
hope this helps
Answer:
The answer is x=2
Step-by-step explanation:
81∧x = 3∧x + 6
3∧4x = 3∧x + 6
4x = x + 6
4x - x = 6
3x = 6
x = 2
