Answer:
(5x + 2)
may be correct answer!
Answer:
(5x + 2)
Step-by-step explanation:
The product of (ax + b) and (cx + d) is:
(ax + b) (cx + d) = ac x² + (ad + bc) x + bd
The leading coefficient is the product of the coefficients of each factor.
The constant is the product of the constants of each factor.
So if (x − 6) is a factor of 5x² − 28x − 12, the other factor must have a coefficient of 5 and a constant of 2.
(5x + 2)
