x3+13x2=-22x
add 22x to both sides:
x3+13x2+22x=0
now factor:
x(x2+13x+22)=0
x(x+11)(x+2)=0
x=0
x+11=0
x+2=0
Therefore the solution to this equation is x=0, x=-11, x=-2

z=pq
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
why will the equations x+14=37 and x-14=37 have different solutions for x
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
3x-2 = 2x+3 3x-2x = 3+2 x = 5
