Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Finding the X-intercept.
1.) Solve for x by substituting 0 in for y.
4x+(0)=5
4x/4+5/4
x=1.25 or 1 and 1/4.
