Question

4(a - 1)2 - 4(a - 1) - 3​

Answer 1

Hey there!

ㅤ

Answer:

→ $\sf{4(a - 1)(2) - 4(a - 1) - 3}$

ㅤ

Distributing both the sides of equation:

→ $\sf{8a + -8 + (-4)(a) + (-4)(-1) + -3}$

→ $\sf{8a + -8 + -4a + 4 + -3}$

ㅤ

Combining like terms from the equation:

→ $\sf{8a + -8 + -4a + 4 + -3}$

→ $\sf{(8a + -4a) + (-8 + 4 + -3)}$

→ ${\boxed{\bold{4a + -7}}}$
