what are the solutions of 8x^2 + 4x+1=0 ? pleaseeee help me i really just want to know how to solve it-x= -4+ or - sq rt of 16-4(8)(1)/ 2(8)
-4 + or - sq rt of -16/ 16
-4+ or -4i/16
-1 + 1i/4or-1 -
This is the question:
Factor:
y^4(y + 2)^3 + y^5(y + 2)^4
This was the answer I was given:
y^4*(y+1)^2*(y+2)^3
I dont understand how it ended up there-Make a small change
y + 2 = A
=> y^4A^3 + y
I totally forgot about these, i dont even know what the generic problem looks like.
Could some tell me:
-what a problem would like
-the name of these problems
-how to solve these problems
-how to do
if α and β are roots of x^2 + 5x + 7 = 0 form the quadratic equations whose roots are (α^2-β^2) and (α^2+β^2)
i got that α+β=-5 and αβ=7
which equate the two roots
(α-β)^2 = 25 - 14 --> = 11
(α+β)^
the thing is that my teacher is taking test today evening so wanna know how to middle term split.
i heard there is a formula to do so-take for example ----------x^2 - 3x +2now wehave to split-3 in suc

a) Let the function f(x) = e^(-2x).
Find a simple exact value for f(In3)
b) Let the function f(x) = e^x + 3e^(-x)
Find a simple exact value for f(In2)-remember that e^lna = a, and blna = ln(a^b)

1. multiply me by 3, then add 3.divide by 5 then subtract 4. the final answer is 2.
2. divide 24 by me then multiply by 5. subtract 7 and multiply by 7. you get 56
3. divide me by 5 subtract 9 then mu
