Find the smallest zero for the function h(x) =4x squared -8x-60

The smallest zero is

Step-by-step explanation:

The given function is

To find the zeros of this function, we equate it to zero.

Dividing through by 4 gives

We split the middle term to get;

Factor

Factor further to get;

The zeros are

The smallest zero is

associative property of multiplication

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
