Question

6. Multiply :(2m(-)) {-3m+(-5)​

Answer 1

Answer:

Step-by-step explanation:

Given

We have given m= 1 & n=-1

To Find

we have to find value of product

⇢(2m+(-n) by (-3m+(-5))

First step is to solve values inside brackets.

⇢(2m-n) by (-3m-5)

⇢(2m-n)×(-3m-5)

we have solved values inside brackets.Now, Multiply each and every values of first term with the second term.

⇢2m(-3m-5) -n(-3m-5)

⇢-6m²-10m+3mn+5n

Now, we obtained the Equation

Put m = 1 & n= -1 into equation

⇢-6(1)²-10(1)+3(1)(-1)+5(-1)

⇢6-10-3-5

⇢-4-8

= -12

Hence,value of product is -12
