Neither of the solutions appears on the list you provided along with the question.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
15,000 to the third power that equals pi plus 12 would make it the square root of 7

-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
(x, y) = (3, 7) is a solution.
x = 3 and y = 2
2x^(2) - 5x - 12 First write down all the factors of '2' & '12' 2 = 1,2 12 = 1,12; 2,6; 3,4 . From this we select two pairs of numbers, one pair from each coefficient, that add/multiply to '5' They are, 1,2 & 3,4 Hence -(2 x 4) + (1 x 3) = -8 + 3 = -5 Set up the brackets (2x 3)(x 4) Hence the signs are ( 2x + 3)(x - 4)
the empty set.
2X2+5x-12 4+5x-12 -8+5x 5x-8
