A quadratic equation can be written as: ax² + b.x + c =0
But if you know the values of the 2 roots x' and x", you can write it:
a(x-x')(x-x"), Since the roots are given ( x' = -4 and x" = -5) and also a (=2)
then the equation becomes:
2(x + 4)(x +5) =0
Answer:
start with the parenthesis
The answer is D!
I hope this helps you, and don't forget to give this answer brainliest if it really helped!
Answer:
Equation of line:
Step-by-step explanation:
We have given,
Slope of line =
y intercept equal to that of a line y =
i.e, y intercept = -2 {Plug x = 0 in the line equation}
Hence we have a slope = and y intercept = -2.
That means , equation of line will be formed as:
And we can also plot this line on a graph.
