Question

27x2-20x+4 factorise​

Answer 1

$27 \times 2 - 20 \times 4 \\ = 54 - 80 \\ = - 24 \:$

Solution

Answer 2

Step-by-step explanation:

27x²-20x+4

To find x

$x = ( - b± \sqrt{b {}^{2} - 4ac } ) \div 2a$

x=[-(-20)±√{(-20)²-4(27)(4)}]/2(27)

x=(20±√400-432)/54

x=(20±4√2j)/54

x=0.37±0.105j
