Question

5x - 4x (square) + 3. x = 0, x = -1, x = 2​

Answer 1

Answer:

$\sqrt{4} \geq 2$

Step-by-step explanation:

Answer 2

Step-by-step explanation:

(5x - 4x) ^ 2+ 3

When x = 0

(5*0 - 4*0) ^2 + 3

(0 - 0)^ 2+3

0+3 =3

When x = - 1

(5*-1 - 4*-1)^2 + 3

(-5 +4) ^ 2 + 3

(-1) ^ 2 + 3

1 + 3 = 4

When x = 2

(5*2 - 4*2) ^ 2 +3

(10-8) ^2 + 3

(2) ^ 2 + 3

4 + 3 = 7
