Question

check whether the following are quadratic equations
(x+1)² = 2(x_3)​

Answer 1

Answer:

no the equations are not equal to each other ok?

Answer 2

Answer :

• It's a Quadratic equation

Given :

• (x + 1)² = 2(x - 3)

To find :

• Quadratic equation

Solution :

》(x + 1)² = 2(x - 3)

we know that,

• (a + b)² = a² + b² + 2ab

》x² + 1² + 2 × x + 1 = 2(x - 3)

》x² + 1 + 2x = 2x - 6

》x² + 1 + 2x = 2x + 6 = 0

》x² + 1 + 6 = 0

》x² + 7 = 0

》x² + 0 + 7 = 0

So, it's a Quadratic equation

Where , a = x , b = 0 , c = 7

More Explanation :

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² - b² + 2ab
• a² - b² = (a + b) (a - b)
