Question

Resolve into factors: 7x² − 19x − 6​

Answer 1

Answer:

7x² − 19x − 6​=(7x-2) (x+3)

Step-by-step explanation:

7*6=42

factors of 42=1, 2, 3, 6, 7, 14, 21, 42

21-2=19

so,

7x^2+21x-2x-6

7x(x+3)-2(x+3)

(7x-2) (x+3)

Mark as brainliest, I didn't copy paste, solved by myself

Have a great day! :)

Answer 2

Answer

7x 2−19x−6=0

⇒7x 2−21x+2x−6=0

⇒7x(x−3)+2(x−3)=0

⇒(7x+2)(x−3)=0

Now, this means either (7x+2)=0 or (x−3)=0.

7x+2=0

⇒x= 7−2 x−3=0

⇒x=3
