Question

X²-2x-25=0 solve by factorising method

Answer 1

Answer:

it will not solve by factorising method

Answer 2

Answer:

at first we have to use the splitting method...

x²- 2x ‐25 =0

subtract 25 from both sides

x²+2x-25

add 1 on both sides

-25+1 or -25/1+ 1/1 = -24/1

now adding so finally we get;-

x²+2x+1=-24

x²+2x+1

(x+1) (x+1)

(x+1)² = answer............
