Which of the following is a situation in which an equation can not be solved using the quadratic formula

Complete question is

Which of the following is a situation in which an equation cannot be solved using the quadratic formula?  (a) The coefficient of the x^2-term is 1.

(b)The right-hand side of the equation is zero.

(c)One term of the polynomial has a degree of 3.

(d)The coefficient of the x-term is zero.

Answer :

(a) The coefficient of the x^2-term is 1 =>  we can use quadratic formula for any coefficient of x^2 term.

(b)The right-hand side of the equation is zero. => we can apply quadratic formula only when the right side of the equation =0

(c)One term of the polynomial has a degree of 3. => the highest degree of quadratic equation is 2. So we cannot apply quadratic formula for polynomial that has degree 3.

(d)The coefficient of the x-term is zero => we can apply quadratic formula but x^2 term should be there. 0 in x term does not affect the formula.

So answer is C

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
