You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.

You simplify expressions and solve equations. You don't simplify something that has an equal sign, and you don't solve something that doesn't have an equal sign. For examples, you simplify 2/4 and solve x + 0 = 1
to solve 18-70 you would subtract just like any other equation. 18-70 is equal to a negative number, -52.
To solve for intercepts on a straight line graph put the equation in the form y=mx+c where c is the y-intercept and you have the y intercept. Now to solve x-intercept set y=0 eg y=2x+5 0=2x+5 2x=-5 x=-2.5 For intercepts on other forms of graphs eg parabola y-intercept= make x equal to 0 and solve x-intercept= make y equal to 0 and solve

0 = 1 is incorrect
Actually, you wouldn't be able to solve that problem. 0/x would equal 0 but x/0 does not have a solution. The common phrase in this is "undefined."
Set it equal to 0 and subtract x and solve for y

All you do is set the quadratic function to equal to 0. Then you can either factor or use the quadratic formula to solve for your unknown variable.

sinx(1-sinx)=0 sinx=0 or 1 x= 0, 90, 180, 270, 360...
what does the equation equal? if it equals zero: 0= 3x(4-11) 0=3x(-7) 0=3x 0=x if the equation doesn't equal anything, it means it's just an expression meaning you can't solve for x, you can only reduce (and this equation is already reduced). if the equation equals y, you need another equation and use either substitution or elimination to solve for x.
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
