Answer:5
Step-by-step explanation:
The solutions of the equations are -1.3 and -7.7
Step-by-step explanation:
The quadratic formula of solving the quadratic equation
ax² + bx + c = 0, where a, b and c are constant is:
To solve the quadratic equation by using the quadratic formula
1. Find the values of a , b and c from the equation
2. Substitute the values of a , b and c in the quadratic formula
3. Find the two values of x
∵ x² + 9x + 10 = 0
∴ a = 1 , b = 9 and c = 10
∵ 
∴ 
∴ 
∴ x = -1.3
∵ 
∴ 
∴ 
∴ x = -7.7
The solutions of the equations are -1.3 and -7.7
