Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
There's the answer what you do is
5x2=10 2/10 3/15 5/25 8/40
Answer:
12y + 11
Step-by-step explanation:
To add them you would add like terms. That means you would add those with y together and those without together.
8y + 4y + 6 + 5 = 12y + 11
If you want to solve for y, subtract 11 from both sides then divide both sides by 12.
Inequality can be used to find the domain of f(x) is x ≥ -
f(x) =
for real f(x)
4x + 9 ≥ 0
⇒ x ≥ -
Thus, Inequality can be used to find the domain of f(x) = is x ≥ -
