Question

(iv) (x-3)(2x+1)= x(x+5)​

Answer 1

Your Answer :-

In this Question, We have To Factorise The Term Given.

• $\bf{(x - 3)(2x + 1) = x(x + 5)}$

• $\bf{2 {x}^{2} + 1 - 6x - 3 = {x}^{2} + 5x}$

• $\bf{2 {x}^{2} - {x}^{2} - 6x - 5x = 3 - 1}$

• $\bf{ {x}^{2} - 11x = 2}$

• $\bf{{x}^{2} - 11x - 2 = 0}$

So, The Answer :- x²-11x-2.

Answer 2

Answer:

x²-10x-3=0

Step-by-step explanation:

=(x-3)(2x+1)= x(x+5)

=2x²+x-6x-3=x²+5x

=2x²-5x-3=x²+5x

=x²-10x-3=0
