Question

5xsquare -19x+18=0 facterisation method​

Answer 1

Step-by-step explanation:

5x² - 19x + 18 = 0

5x² - 10x - 9x + 18 = 0

5x ( x - 2) - 9 ( x - 2) = 0

( 5x - 9 ) ( x- 2) = 0

either,

5x - 9 = 0

5x = 9

x = 9 /5

or,

x-2 = 0

x = 2

Answer 2

Answer:

x=2,x=9/5

Step-by-step explanation:

5x^2-19x+18=0

Using Quadratic Equation:

= -b√b^2-4ac/2a

a= 5,b= -19,c= 18

x= -(-19)+√(-19)^2 -4*5*18/2*5

x=2

x= -(-19)-√(-19)^2 -4*5*18/2*5

x=9/5
