Question

Find the value of 'm' if the quadratic equation has equal root
x² - (m+2) x + m +5=0.​

Answer 1

Answer:

4

Step-by-step explanation:

x2-(4+2)x+4+5=0

x2-6x+9=0

x2-3x-3x+9=0

x(x-3)-3(x-3)=0

x-3=0

x=3

Answer 2

Answer:

for equal roots

b²-4ac=0

[m+2]²-4[m+5]=0

m²+4+2m-4m-20=0

m²-2m-16=0
