Question 967848
y = 4x^2 + x + 2
it's a quadratic so you can factor it.
easiest way is to graph it.
graph looks like this:
{{{graph(400,400,-10,10,-10,10,4x^2+x+2)}}}
it doesn't cross the x-axis.
without graphing, you would have had to solve.
give it the discriminant test.
discriminant is b^2 - 4ac
equation is 4x^2 + x + 2 = 0
a = 4
b = 1
c = 2
b^2 - 4ac = 1 - 4*4*2 which is negative.
distriminant is negative so the roots are not real.
roots are not real so the graph goesn't cross the x-axis.
