User: Solve the quadratic equation y2 - 5y = -4 by factoring.

Weegy: The answer is "real and irrational root" ;
Solution:
discriminant of ax^2 + bx + c = 0 is b^2 - 4ac
if D = 0 double root
D 0 and is a perfect square - - - -real and rational distinct roots
D>0 and is not a perfect square - - - -real and irrational [ [ distinct roots
here D = 5^2 - 4*1*(-3) = 25 + 12 = 37
not a perfect square
so therefore it is a real and irrational root . ] ] Expert answered|ambermendez|Points 0|

The "point-slope" form of the equation of a straight line is: y - y1 = m(x - x1) thus y - 1 = 6 (x - 0) Simplify the equation we get y = 6x + 1 The line with slope m = 6 including point (0, 1) is y = 6x + 1
