Question

5x_(4x_7)(3x_5)=6_3 (4x_9)(x_1)​

Answer 1

Answer:

∴  85x - 24x² = 62

Explanation:

5x - (4x-7) (3x - 5) = 6-3 (4x -9) (x-1)

or, 5x - { 4x(3x -5) - 7(3x-5)} = 3 { 4x(x-1) - 9(x-1)}

or, 5x- ( 12x² - 20x - 21x+ 35) = 3 (4x² - 4x - 9x + 9}

or, 5x - (12x² -41x + 35) = 3 (4x² - 13x+9)

or, 5x - 12x² + 41x - 35 = 12x² - 39x + 27

or, 46x - 12x² -35 = 12x² - 39x +27

or, 46x + 39x - 12x² - 12x² - 35 - 27 = 0

or, 85x - 24x² - 62 = 0

∴  85x - 24x² = 62
