Question

Alessandro wrote the quadratic equation –6 = x2 + 4x – 1 in standard form. What is the value of c in his new equation?

Answer 1

Hello,

Given equation-

-6= x2 + 4x – 1

Transferring sides,

x2 + 4x -1 +6 = 0

x2 + 4x + 5 = 0

Comparing it with standard form ax2 + bx +c = 0 , we get

a = 1

b = 4

c = 5

So your answer would be c = 5 .
