It is a quadratic expression which can't be factored because its discriminant is less than zero
88=13+5x -13 -13 75= 5x 75/5 =15 x=15
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
The given quadratic expression can not be factorized because its discriminant is less than zero.
It has no solutions because the discriminant of the quadratic equation is less than zero.
3x - 7 = 5x + 13-2x = 20x = -10
