You can put this solution on YOUR website!

1.
3x%5E2+-48+=+0
3x%5E2+=48
x%5E2+=48%2F3
x%5E2+=16
x+=sqrt%2816%29
x+=4 or x+=-4

2.
x%5E2+=+sqrt%2836%29
x+=+36
x+=6 or x+=-6
3.
p%5E2+-50+=+0
p%5E2+=50+
p+=sqrt%2850%29+
p+=sqrt%282%2A25%29+
p+=sqrt%282%2A5%5E2%29+
p+=5sqrt%282%29+ or p+=-5sqrt%282%29+
