Question

for what value of m, Equation mex ² + 2 (M+1)+4
have equal zeroes.​

Answer 1

Step-by-step explanation:

• Mx² + 2(M + 1) + 4
• Mx² + (2M + 3) + 4
• Mx² + 2M + 7

Let,

• a = M
• b = 2
• c = 7

Discriminant (D) = 0

• b² - 4ac = 0
• (2)² - 4 × m × 7 = 0
• 4 - 28m = 0
• -28m = -4
• m = -4 / -28
• m = 7
