Algebraically, with X = ' what. '30X = 180X = 180/30X = 6=====
3x2 + 30x + 48 is a quadratic polynomial. If 3x2 + 30x + 48 = 0, then: 3(x + 2)(x + 8) = 0 ⇒ x + 2 = 0 → x = -2 or x + 8 = 0 → x = -8
3y plus 6x = 2
60x + 120x - 40x - 80x - 30x = 24030x = 240x = 240/3 = 80
9 plus 7 equals 144. Generally, x plus y = x(x+y).
