Can some do this plzz

Step-by-step explanation:

When you factor each equation, you result in two of the factors canceling out, resulting in .

[Top Equation]

The middle number is 3 and the last number is -28.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 3

Multiply together to get -28

Can you think of the two numbers?

Try -4 and 7:

-4+7 = 3

-4*7 = -28

Fill in the blanks in

(x+_)(x+_)

with -4 and 7 to get...

(x-4)(x+7)

[Bottom Equation]

The middle number is -7 and the last number is 12.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -7

Multiply together to get 12

Can you think of the two numbers?

Try -3 and -4:

-3+-4 = -7

-3*-4 = 12

Fill in the blanks in

(x+_)(x+_)

with -3 and -4 to get...

(x-3)(x-4)

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
