Question 867148
a. 2x² - 2x + 2 = 4
b. 2x² - 2x = 10 
both a and b can be reduced by dividing both sides of = by 2
a. x² -x + 1 = 4
x² -x - 3 = 0
b. x² -x = 5
x² -x - 5 = 0
the graph looks like
{{{ graph( 300, 200, -10, 10, -10, 10, x^2 -x -3, x^2 -x -5 ) }}}
function a is the red curve and function b is the green curve
these curves do not intercet, so there is no solution
