Answer 1

Answer:

Simplifying

(5a + -3b)(a + b) = 0

Multiply (5a + -3b) * (a + b)

(5a * (a + b) + -3b * (a + b)) = 0

((a * 5a + b * 5a) + -3b * (a + b)) = 0

Reorder the terms:

((5ab + 5a2) + -3b * (a + b)) = 0

((5ab + 5a2) + -3b * (a + b)) = 0

(5ab + 5a2 + (a * -3b + b * -3b)) = 0

(5ab + 5a2 + (-3ab + -3b2)) = 0

Reorder the terms:

(5ab + -3ab + 5a2 + -3b2) = 0

Combine like terms: 5ab + -3ab = 2ab

(2ab + 5a2 + -3b2) = 0

Solving

2ab + 5a2 + -3b2 = 0

Solving for variable 'a'.

Factor a trinomial.

(5a + -3b)(a + b) = 0

Answer 2

Step-by-step explanation:

(5a-3b)(a+b)

5a(a+b)-3b(a+b)

5a²+5ab-3ab+3b²

5a²+2ab-3b²
