Discriminant of quadratic equation ( ax² + bx + c = 0 ) could be calculated by using :
<h2>D = b² - 4 a c</h2>
From the value of Discriminant , we know how many solutions the equation has by condition :
D < 0 → No Real Roots
D = 0 → One Real Root
D > 0 → Two Real Roots
An axis of symmetry of quadratic equation y = ax² + bx + c is :
Let us now tackle the problem!

Answer:
yes, the question is proportional. if you multiply 9.50 by 2 you get 19 and so on and so forth. the constant rate is 9.50
Answer:
x = -6 and -1
Step-by-step explanation:
x^2 + 6x + 7
Factorise- find two numbers that multiply to be 6 and add to be 7: 6 and 1
(x+6)(x+1)
Set each expression equal to 0 and solve
x + 6 = 0 -> x = -6
x + 1 = 0 -> x = -1
