Hmm. not sure if question is written correctly. we dont need the quad formula for this can just solve by
4z^2-7=0
4z^2=7
z^2=7/4
and z=+- sqrt7/2

you can use the quad formula with a=4 b=0 and c=-7
put this into (-b+-sqrt(b^2-4ac))/(2a)
will get the same answer.

if.tou like my answer plz rate as brainliest thx

Which number is a solution of the inequality 8 - 1/4 b &gt; 27
Brrunno [24]

The inequality is 8-1/4x>27. The solution of the inequality is b<-76.

Given that,

The inequality is 8-1/4x>27

We must determine how to address the inequity.

Take,

8-1/4x>27

Multiply the inequality's two sides by its lowest common denominator,

4×8-4×1/4b>27×4

Reduce the expression to the lowers term,

4×8-b>4×27

Calculate the product or quotient,

32-b>4×27

Calculate the product or quotient,

32-b>108

Rearrange unknown terms to the left side of the equation,

-b>108-32

Calculate the sum or difference,

-b>76

Divide the inequality's two sides by the variable's coefficient,

b<-76

Therefore, the solution of the inequality is b<-76.
