Question

find the value of c so that equation four x square minus 2 into c + 1 into x + c + 4 is equal to zero has real and equal roots​

Answer 1

Answer:

Step-by-step explanation:

x² - (2c+1)x + c+4 = 0

Let the roots be R and R

ie, x² - (2c+1)x + c+4 =  (x-R) (x-R)

2R = 2c+1 and R² = c+4

ie, 2R = 2(R²-4) + 1

2R² - 2R - 7 = 0

R² - R - 7/2 = 0

Solving this equation, we will get imaginary solutions. Please check the question.
