Question

(x + 5)^2 = 2 (5x - 3)​

Answer 1

Answer:

SOLUTION

Given the quadratic equation is (x + 5)2 = 2 (5x − 3).

⇒ x2 +25 +10x =10x -6

⇒ x2 + 31 = 0

⇒ x2 +0x +31 = 0

So, the discriminant will be

D =b2 -4ac

= 02 - 4 × 1 × 31= -124

Answer 2

taking lhs
(x+5)^2. (a+b)^2=a^2+b^2+2ab
x^2+25+10x


now rhs,
10x-6
