expand r(1.16-0.58r+0.298r^2=0)

expand

r (1.16 - 0.58 r + 0.298 r^{2} = 0)

0.298 r^{3} - 0.58 r^{2} + 1.16 r = 0

Solution steps

r (1.16 - 0.58 r + 0.298 r^{2} = 0)

= r (1.16 - 0.58 r + 0 \cdot 0.298 = r^{2})

Distribute parentheses

r \cdot 1.16 + r (- 0.58 r) + r \cdot 0.298 r^{2} = 0

Apply minus-plus rules

+ (- a) = - a

1.16 r - 0.58 rr + 0.298 r^{2} r = 0

Expand

1.16 r - 0.58 rr + 0.298 r^{2} r : 0.298 r^{3} - 0.58 r^{2} + 1.16 r

0.298 r^{3} - 0.58 r^{2} + 1.16 r = 0
