$y=3x^4 -4x^3 -12x^2 +1\\
y'=12x^3-12x^2-24x\\\\
12x^3-12x^2-24x=0\\
12x(x^2-x-2)=0\\
12x(x^2+x-2x-2)=0\\
12x(x(x+1)-2(x+1))=0\\
12x(x-2)(x+1)=0\\
x=0 \vee x=2 \vee x=-1\\\\
\forall{x\in(-\infty,-1)\cup(0,2)}\ y'$
$y(-1)=3\cdot(-1)^4-4\cdot(-1)^3-12\cdot(-1)^2+1=3+4-12+1=-4=\\

A=1/2(b1-b2)h <br><br> Solve for h

Phantasy [73]

Answer:

2A/ (b1-b2) =h

Step-by-step explanation:

A = 1/2 (b1-b2) *h

Multiply each side by 2

2A = 2 *1/2*(b1-b2) *h

2A = (b1-b2) *h

Divide by (b1-b2)

2A/ (b1-b2) = (b1-b2)/(b1-b2) *h

2A/ (b1-b2) =h
