Answer:

m = 8

Explanation:

Expand the left side

Each term in the second factor is multiplied by each term in the first factor

7a²(4a² - 1) + 2a(4a² - 1) - 3(4a² - 1) ← distribute parenthesis

= 28
a^(4) - 7a² + 8a³ - 2a - 12a² + 3 ← collect like terms

= 28
a^(4) + 8a³ - 19a² - 2a + 3

Comparing the coefficients of like terms with those on the right , then

m = 8
