Answer:
A). 2x^2(2x^2 + 5x + 1)
B). (x + 6)(x + 7)
Step-by-step explanation:
A). 4x^4+10x^3+2^2
I assume the problem is
4x^4 + 10x^3 + 2x^2
Look at he number parts, 4, 10, 2. They have a common factor of 2.
Now look at the variable parts, x^4, x^3, x^2. They have a common factor of x^2.
We factor out 2x^2 from every term.
4x^4 + 10x^3 + 2x^2 =
= 2x^2(2x^2 + 5x + 1)
B). x^2 + 13x + 42
We need to find two numbers whos product is 42 and whose sum is 13. The numbers are 6 and 7.
x^2 + 13x + 42 =
= (x + 6)(x + 7)
