i need help solving math promblemf(x)=x to the power of x2-12x+44
Accepted Solution
A:
Did you mean: "find the roots of f(x) = x^2 - 12x + 44?"
If so, notice that a=1, b= -12 and c=44.
According to the quadratic formula,
-b plus or minus sqrt(b^2 - 4ac) x = ---------------------------------------------- 2a
Here, with a=1, b= -12 and c=44,
12 plus or minus sqrt([-12]^2 - 4[1][44]) x = ------------------------------------------------------- 2[1]
This simplifies to
12 plus or minus sqrt(144-176) x = ------------------------------------------- 2 12 plus or minus sqrt( -32) = --------------------------------------- 2
