Where is the point t in question
Answer:
u= -449
Step-by-step explanation:
714=6(u+629)-366
<u>+366 +366</u>
1080=6u+3774
<u>-3774 -3774</u>
6u=-2694
<u>÷6 ÷6</u>
u=-449
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:
