2x2 + 10x - 3
The discriminant is defined as b2 - 4ac, so for this function b=10, a=2, and c=-3
So the discriminant is 100-4*2*-3 = 124

72-4*3*4 = 1
b^2 - 4ac Is the discriminant. 6^2 - 4(3)(5) 36 - 60 = - 24 < 0 so, an unreal answer and no real X intercepts
It can't be factored because the discriminant is less than zero.
The discriminant is b^2-4ac. So, b=7, a=2, and c=3. 7^2=49-4(2)(3)=49-24=25. So the discriminant is 25.
The discriminant is..... b^2 - 4ac (-2)^2 - 4(3)(3) 4 - 36 = - 32 Less than 1 so no real roots.
