Question

If 22 - b + c = 0, prove that 402 – 52 + 2 + 4ac = 0.
Hint. 2a-b+c=0= 2a + C = b = 2a + c)2 = 62.​

Answer 1

Step-by-step explanation:

In order to prove that 4a^2-b^2+c^2+4ac=0 (eq2) It will be enough to prove that this equation is equal to the given equation(eq1) :

4a^2+c^2+4ac=b^2

(2a+c)^2=b^2

2a+c=b

2a+c-b=0

From this we get eq1=eq2

Hence proved.
