Question 171868
how do you use the quadratic formula for 2a^2 - 46a + 252 = 0? please round to the nearest hundreth
---------------------
2a^2 - 46a + 252 = 0
Divide by 2.  
Always reduce when possible, it makes it easier to spot factors, and, if you do it by hand, it makes the numbers you deal with smaller.
a^2 - 23a + 126 = 0
*[invoke solve_quadratic_equation 1,-23,126]
So it's 14 and 9.  The solver always uses x, sub a for x.
