Question

equation X + 1 whole square plus x square is equal to zero has – roots​

Answer 1

Answer:

This equation has no real roots.

Step-by-step explanation:

(x + 1)² + x² = 0

x² + 2x + 1 + x² = 0

2x² + 2x + 1 = 0

In this equation, a = 2, b = 2 and c = 1

If b² - 4ac < 0, then the equation has no real roots.

If b² - 4ac = 0, then it has equal roots.

If b² - 4ac > 0, then it has 2 different positive roots.

Substituting values for a, b and c in this formula

b² - 4ac = 4 - 8 = -4 < 0

Hence, this equation has no real roots.
