The descriminant is b^2-4ac so for 26 it would be -5^2 - 4 (1) (7). The quadratic formula is -B plus or minus the square root of b squared minus 4ac over 2a
Y= -3/5x - 2 Add -3/5x to both sides 3/5x +y= -2 Multiply both sides by 5 because 5 is the denominator. By multiplying by 5 you can cancel out and make it a real number. 5(3/5x +y) = -2(5)
