Question

2y³ – 5y² – 19y +42 in factor theorem ​

Answer 1

Step-by-step explanation:

2y^3–5y^2–19y+42

2y^2(y–2)–y^2–19y+42

2y^2(y–2)–y(y–2)–21y+42

2y^2(y–2)–y(y–2)–21(y–2)

(y–2)(2y^2–y–21)

(y–2)(2y–7)(y+3) ANSSSSSSSSSSSSSSSSSS SSSSSSSSSSS SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

Answer 2

Answer:

2y^3–5y^2–19y+42

2y^2(y–2)–y^2–19y+42

2y^2(y–2)–y(y–2)–21y+42

2y^2(y–2)–y(y–2)–21(y–2)

(y–2)(2y^2–y–21)

(y–2)(2y–7)(y+3)
