(x^2 + 6x -x -6) - (x^2 -3x -2x +6) = x^2 +5x -6 - x^2 +5x -6 = 10x -12 = 0, 10x = 12, x = 12/10, x = 6/5 ( second question answer) , Q1 is not clear

in question 1 its' given that (x+5)whole square multiplied by(x+2)whole square which is equal to -2

(x -5) ^2 can be = x ^2 + 25 -10x and (x +2 ) ^2 can be written as x ^2 + 4 + 4x , when we multiply this we get x ^4 + 4x ^3 + 4x^2 +25x ^2 + 100 +100x -10x^2 -40x -40x^2 = -2 , then we get the answer as x^4 + 4x^3 -39x^2 + 60x + 102
