Question

factorise 75x square -60x+12 ​

Answer 1

Answer:

Factor. Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=5x a = 5 x and b=2 b = 2 .

Answer 2

Step-by-step explanation:

$75 {x}^{2} - 60x + 12 = 0 \\ = > 75 {x}^{2} - 30x - 30x + 12 = 0 \\ = > 15x(5x - 2) - 6(5x - 2) = 0 \\ = > (5x - 2) \times (15x - 6) = 0 \\ = > x = \frac{2}{5} \: or \: \: x = \frac{6}{15} = \frac{2}{5}$
