Question

factorise the following​

Answer 1

Answer:

( x + 1 )  ( 1 - x )

Step-by-step explanation:

by splitting the middle term

i.e.

2x² - 2x + x + 1

-2x ( x +  1 ) + 1 ( x + 1 )

( 1 - 2x ) ( x + 1)

Answer 2

Answer:

Step-by-step explanation:

2x∧2 - x + 1

a = 2 b = -1 c = 1

Use quadratic formula

x = -b±√(b∧2 - 4ac) ÷ 2a

x = -(-1)±√(-1)∧2 - 4(2)(1) ÷ 2(2)

x = 1±√(1 - 8) ÷ 4

x = 1±√(-7) ÷ 4

x = 1 + √7 ÷ 4 OR x = 1 - √7 ÷ 4
