Question

Hi,
can anyone help me with these questions. Please no spam, please. I have Test Tomorrow.

Answer 1

I have submitted you first 2 answers so do last q by your own to learn how to solve. all the best for the test.

we need to think of 2 numbers such that:

N1 × N2 = a × c=1 × ( −8 ) = −8

and

N1 + N2 = b = −2

After trying out a few numbers we get

N1=−4

and

N2 = 2 − 4 × 2 = −8 and

2 + (−4 ) = −2

x² − 2x − 8 = x² − 4x + 2x − 8

==========> x ( x − 4 ) + 2 ( x − 4 )

==========> ( x + 2 ) ( x − 4 )

Answer 2

Step-by-step explanation:

last question last step

product =alpha. beta =c/a

4/3×-1 =-4/3

-4/3. = - 4/3

All the best
