Answer:
(y -5)(y -i√6)(y +i√6)
Step-by-step explanation:
The expression can be factored by grouping:
(y^3 -5y^2) +(6y -30) = y^2(y -5) +6(y -5) = (y^2 +6)(y -5)
The quadratic factor is the difference of squares, if you consider -6 to be a square. In that view, it can be factored as ...
y^2 +6 = (y -i√6)(y +i√6)
Then the complete factorization is ...
(y -5)(y -i√6)(y +i√6)
Algebraically that would be expressed as 2r + 11
The product of 2 and r is 2r.
The sum of 2r and 11 is 2r + 11
251/50 or mixed number is 5 1/50
Answer: y > 4.5 or y < -4.5
You use the rule
if |y| > k, then y > k or y < -k
where k is some positive number. In this case, k = 4.5
Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
