F(x) = 3x3 – 2x2 + x - 4 at x = -3

Yuri [45]

Steps to solve:

f(x) = 3x³ – 2x² + x; x = -3

~Substitute

f(-3) = 3(-3)³ - 2(-3)² + (-3)

~Solve the exponents

f(-3) = 3(-27) - 2(9) + (-3)

~Multiply

f(-3) = -81 - 18 - 3

~Subtract

f(-3) = -102

Best of Luck!

How do you factor m^2=2m?<br><img src="https://tex.z-dn.net/?f=m%20%5E%7B2%7D%20%20%3D%202m" id="TexFormula1" title="m ^{2} = 2

Sonbull [250]

First move all terms to one side:

$m^2=2m\implies m^2-2m=0$

Then all terms on the left side share a common factor of $m$ :

$m(m-2)=0$

The zero product product property says that if $ab=0$ , then $a=0$ or $b=0$ . So either $m=0$ or $m-2=0\implies m=2$ .
