Answer

C

11

Step-by-step solution

2 steps

Here are the solutions to the questions:

I.i. The value of the algebraic expression 2x2−10x\frac{2x^2-10}{\sqrt{x}} at x=4x=4 is:

  1. Substitute x=4x=4 into the expression.

    2(4)2−104\frac{2(4)^2-10}{\sqrt{4}}

  2. Simplify the expression.

    2(16)−102=32−102=222=11\frac{2(16)-10}{2} = \frac{32-10}{2} = \frac{22}{2} = 11

    The correct option is C) 11.

    I.ii. One of the Factor of the expression x2−4x+3x^2-4x+3
