The value of expression is,
⇒ (2m - 8)² = 4m² - 24m + 64
An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The expression is,
⇒ (2m - 8)²
Now,
We know that,
The formula is,
⇒ (a - b)² = a² - 2ab + b²
Hence, We get;
⇒ (2m - 8)² = (2m)² - 2 × 2m × 8 + (8)²
= 4m² - 24m + 64
Thus, The value of expression is,
⇒ (2m - 8)² = 4m² - 24m + 64
