Find the zeros of f(x) = 4x 2 + 5x - 21.
a.) {-7/4, 3}
b.) {7/4, -3}
c.) {3/4, -7}

ANSWER

The correct choice is B

EXPLANATION

The given function is

To find the zeros, we equate the function to zero.

We split the middle term to get:

Factor by group,

Factor further,

Use the zero product property,

Hence the zeros are:

B.) {7/4, -3}

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
