Question

Simpify
${a}^{2} - 2a + ( {5a}^{2} - (3a - {4a}^{2} ))$
equation. ​

Answer 1

Step-by-step explanation:

a^2-2a+{5a^2-(3a-4a^2)}

=a^2-2a+{5a^2-3a+4a^2}

=a^2-2a+(9a^2-3a)

=a^2-2a+9a^2-3a

=10a^2-5a

=5a(2a-1)

Answer 2

a² - 2a + [5a² - (3a - 4a²)]

= a² - 2a + 5a² - 3a + 4a²
= a² + 5a² + 4a² - 2a - 3a
= 10a² - 5a
= 5a (2a - 1)
