Expression 1

2a (a - 5) + 4(a - 5) = 0 Simplifying

2a (-5 + a) + 4(a - 5) = 0 Reorder like terms

(-5 x 2a + a x 2a) + 4(a - 5) = 0

(-10a + 2a2) + 4(a - 5) = 0

-10a + 2a2 + 4(-5 + a) = 0Applying distributive property of real numbers

-10a + 2a2 + (-5 x 4 + a x 4) = 0

-10a + 2a2 + (-20 + 4a) = 0Remove parentheses

-20 - 10a + 4a + 2a2 = 0

-10a + 4a = -6a Combine like terms:

-20 ...
