Find the values for "a" and "b" that would make the equality true -5(3x^2+5x+b)=ax^2-25x+45 a= b=

a = - 15 and b = - 9

distribute the left side of the equation

- 15x² - 25x - 5b

for - 15x² - 25x - 5b and  ax² - 25x + 45 to be equal then the coefficients of like terms must be equal, hence

- 15x² = ax² ⇒ a = - 15

- 5b = 45 ⇒ b = - 9

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
