<h3>Hope it is helpful...</h3>
A quadratic equation that has 2 roots that are equal means that the discriminant of the equation is 0. The value of k that makes the equation have 2 real and equal roots is
Given that:
Rewrite as:
A quadratic equation is represented as:
By comparison:
If an equation has 2 real and equal roots, then:
So, we have:
Divide by 4
Divide by 6
Subtract 2 from both sides
Take LCM
Divide by 2
Hence, the value of k that makes the equation have 2 real and equal roots is

Answer:
Step-by-step explanation:
As given ,
-5*(a+3) =-55
(-5*a)+(-5*3)= -55

-5a= -55 +15
-5a = -40
a = 8
Answer:
<h2>C. m > -19</h2>
Step-by-step explanation:
3m + 5 > 2(m - 7)
3m + 5 > 2m - 14
