Question

if the sum of the zeros of the quadratic polynomial x2+4kx-3 is 4 then find the value of k

Answer 1

Given :- if the sum of the zeros of the quadratic polynomial x² + 4kx - 3 is 4 then find the value of k ?

Solution :-

we know that, sum of zeros of quadratic equation in the form of ax² + bx + c = 0 , is given by :-

• (-b/a) .

comparing x² + 4kx - 3 = 0 with ax² + bx + c = 0, we get,

• a = 1
• b = 4k
• c = (-3)

so,

→ sum of zeros = 4

→ (-b/a) = 4

→ (-4k)/1 = 4

→ (-4k) = 4

→ k = (-1) (Ans.)

Hence, value of k will be (-1) .
