Question

xsquare-3x+2. x=2 find the answer

Answer 1

2^2-3(2)+2=4-6+2 = 0
mark me brainiest

Answer 2

● Factorisation ●

x² - 3x + 2 = 0

=> x² - 2x - x + 2 = 0

=> x(x - 2) - 1(x - 2) = 0

=> (x - 1)(x - 2) = 0

So,

x - 1 = 0

=> x = 1

when, x = 2,

x² - 3x + 2

= (2)² - 3×2 + 2

= 4 - 6 + 2

= 0

OR

x - 2 = 0

=> x = 2
