Answer 2

$\sf\pink{Solution}$

Given to find the value of x+7+4(x-5)

Where $\sf\green{x=2}$

Substuite value of x in given equation

x+7+4(x-5)

2 + 7 + 4 (2-5)

If given at x = something is a factor means If we substuite that x value it should be equal to LHS=RHS Then only it is called as factor

• A linear polynomial have only 1 factor
• A Quadratic polynomial have only 2 factors
• A cubic polynomial have 3 factors

We can find those factors by using different methods like

Factorisation, complete squaring , by Quadratic formula etc ...
