Question

Solution of this polynomial 4√5x^2-24x-9√5

Answer 1

Answer:

3√5/2 and -3/2√5

Step-by-step explanation:

4√5x^2-24x-9√5=0

4√5x^2-30x+6x-9√5=0

2√5x(2x-3√5)+3(2x-3√5)=0

(2x-3√5)(2√5x+3)=0

x1=3√5/2

x2=-3/2√5

Answer 2

Answer:

x= (3/2)√5, (3/10)√5

Step-by-step explanation:

4√5x²-24x-9√5

= 4√5x²-30x+6x-9√5

= 2√5x( 2x-3√5) +3(2x-3√5)

= (2x- 3√5) ( 2√5x + 3)

x = (3/2)√5. or x = - 3/ (2√5)= 3×√5/10= (3/10)√5

x= (3/2)√5 , x= (3/10)√5
