❤⭐ GOOD NIGHT CURTIS ⭐❤
Step-by-step explanation:
The given quaduric equation is X 2 + 4 x + k = 0 Then find the value ok k.
Here , A = 1 , B = 4 , C = K
As we know that D = b2 - 4ac
Putting the value of A = 1 , B = 4 & C = K
( 4 ) 2 - 4 × 1 × K
= 16 - 4K
• The given equation will have real and district roots. if D > 0 16 - 4 K > 0
4K < 16
K < 16
4
< 4
|| Therefore the value of < 4 ||
