Question:

Compare the given quadratic equations to the general form and write values of a, b, c.

(1) x2 – 7x + 5 = 0

(2) 2m2 = 5m – 5

(3)  y2 = 7y

 

 

 

Answer:

(1) x2 – 7x + 5 = 0

Solution:

Given
x2 – 7x + 5 = 0
comparing with ax2 + bx + c
we get
a = 1, b = -7, c = 5

(2) 2m2 = 5m – 5

Solution:

Given
2m2 = 5m – 5
comparing with ax2 + bx + c
we get
a = 2, b = -5, c = 5

(3)  y2 = 7y

Solution:

Given
y2 = 7y
comparing with ax2 + bx + c
we get
a = 1, b = -7, c = 0
