Solve 3x2 + 4x = 2. TEACH me how to solve this.. I know what to do once I have it in the right forum... but I do not understand

sertanlavr [38]

So if it is 3x^2+4x=2 then
set one side to zero
subtract 2 from both sides
3x^2+4x-2=0
this is not factorable by normal means so use quadratic formula which is if you have the equation in ax^2+bx+c=0 form you can solve for x if you put it into this equation quadratic formula $x=\frac{-b+ \sqrt{b^2-4ac} }{2a} or \frac{-b- \sqrt{b^2-4ac} }{2a}$ so if you were to input it into this equation you would get
a=3
b=4
c=-2

the solution is $x= \frac{-2+ \sqrt{10} }{3} or \frac{-2- \sqrt{10} }{3}$
the answer is C

a(t)=(t−k)(t−3)(t−6)(t+3) is a polynomial function of tt, where kk is a constant. Given that a(2)=0a(2)=0, what is the absolute

Crank

Since $a(2)=0$ , we know that $t-2$ must be a factor of $a(t)$ , so $k=2$ . Then the zeros of $a(t)$ are $t=2,3,6,-3$ , and their product is -108, whose absolute value is 108.
