Rearrange ➡ 3 + 9 × (1 - 5r) - (25)

Step 1. Equation ⬇

(3+9 × (1 - 5r )):- 25 = 0



Step 2. Take out the like terms (factors) ⬇

-45r - 13 = -1 × (45 + 13 )

Equation part 2 ➡ -45 - 13 = 0

Add 13 to both sides of the equation ➡ -45=13

Multiply both sides of the equation by (-1 ) : 45r= -13


divide both sides of the equation by 45

r= -0.289

Answer:

x = 1/3

Step-by-step explanation:

This is in the form

ax^2 +bx+c

a = -3  b = 2  c = -17

The axis of symmetry is at

x = -b/2a

x = -2/ (2*-3)

x = -2/-6

x = 1/3
