Answer:Let's solve your equation step-by-step.

24=x2−4x+3

Step 1: Subtract x^2-4x+3 from both sides.

24−(x2−4x+3)=x2−4x+3−(x2−4x+3)

−x2+4x+21=0

Step 2: Factor left side of equation.

(−x−3)(x−7)=0

Step 3: Set factors equal to 0.

−x−3=0 or x−7=0

x=−3 or x=7

Answer:

x=−3 or x=7

Evaluate the expression 10-2x for the x values given below

cricket20 [7]

For this case we have the following expression:

$10-2x$

Let's evaluate the expression for some values of x.

We have then:

For x = 1:

$10-2 (1)\\10-2\\8$

For x = 2:

$10-2 (2)\\10-4\\6$

For x = 3:

$10-2 (3)\\10-6\\4$

For x = 4:

$10-2 (4)\\10-8\\2$

For x = 5:

$10-2 (5)\\10-10\\0\\$

Answer:

The value of the expression in ordered pairs is:

(1,8)
(2.6)
(3,4)
(4.2)
(5.0)
