Answer:
1)x^2+9x+20
2)x^2-11x+28
1) explaination:x*x+4x+5x+5*4=)x^2+9x+20
2 explaination: x*x+-4*x+-7*x+-7*-4=)x^2-11x+28
Answer:
C is correct
Step-by-step explanation:
To factor:
4x^2 + 12x + 5
(4x^2 + 2x)(10x + 5)
2x(2x + 1) + 5(2x + 1)
Then, take the outside numbers make them their own group:
2x + 5
(2x + 5)(2x + 1)
Therefore, it’s (2x + 1)(2x + 5)
