Write the horizontal intercepts of each function.

$t(x)=-(x+2)(x-4)$

$u(x)=6(x-7)(x-5)$

$v(x)=-2(x+1)(x+4)$

$w(x)=10(x-8)(x+3)$

Solution

The horizontal intercepts of $t$ are $(-2,0)$ and $(4,0)\text{.}$

The horizontal intercepts of $u$ are $(7,0)$ and $(5,0)\text{.}$

The horizontal intercepts of $v$ are $(-1,0)$ and $(-4,0)\text{.}$

The horizontal intercepts of $w$ are $(8,0)$ and $(-3,0)\text{.}$
