Solution for (px+q)(rx+s)=0 equation:


Simplifying
(px + q)(rx + s) = 0

Multiply (px + q) * (rx + s)
(px(rx + s) + q(rx + s)) = 0
((rx * px + s * px) + q(rx + s)) = 0
((prx2 + psx) + q(rx + s)) = 0
(prx2 + psx + (rx * q + s * q)) = 0
(prx2 + psx + (qrx + qs)) = 0
(prx2 + psx + qrx + qs) = 0

Solving
prx2 + psx + qrx + qs = 0

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-1qrx' to each side of the equation.
prx2 + psx + qrx + -1qrx + qs = 0 + -1qrx

Combine like terms: qrx + -1qrx = 0
prx2 + psx + 0 + qs = 0 + -1qrx
prx2 + psx + qs = 0 + -1qrx
Remove the zero:
prx2 + psx + qs = -1qrx

Add '-1qs' to each side of the equation.
prx2 + psx + qs + -1qs = -1qrx + -1qs

Combine like terms: qs + -1qs = 0
prx2 + psx + 0 = -1qrx + -1qs
prx2 + psx = -1qrx + -1qs

Reorder the terms:
prx2 + psx + qrx + qs = -1qrx + qrx + -1qs + qs

Combine like terms: -1qrx + qrx = 0
prx2 + psx + qrx + qs = 0 + -1qs + qs
prx2 + psx + qrx + qs = -1qs + qs

Combine like terms: -1qs + qs = 0
prx2 + psx + qrx + qs = 0
