Answer: the equation is
5x^2 -30x - 25
Step-by-step explanation:
A quadratic equation is one in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where c is a constant and a is the leading coefficient
Assuming we want to write the quadratic equation in x, from the information given, the given roots are 5 and 1 and the leading coefficient is 5. We will just multiply the expression by the leading coefficient.
Therefore, the linear factors of the quadratic will be (x-5) and (x-1)
With the leading coefficient as 5, the equation becomes
5(x-5)(x-1)
= 5(x^2 - x - 5x + 5)
= 5(x^2 - 6x + 5)
= 5x^2 -30x - 25
All the second numbers. {0, 2, 6, 7}.
Answer:
5. p= -4
6. d=4.3

if you need to know how to do it lmk and I'll update it in the step by step explanation!
hope this helped :)
UPDATED
5.
-0.9p+3.2=-1.7p
subtract add 0.9p to both sides
3.2=-0.8p
divide both sides by -0.8 to isolate p
-4=p
6.
-14.3=-1.4-3d
add 1.4 by both sides
-12.9=-3d
divide both sides by -3 to isolate d
4.3=d
