Question

find the product of (5a-2b)(-2a-3b)

Answer 1

Answer:

question-(5a-2b)(-2a-3b)

sol-

Set the factor '(2a + 3b)' equal to zero and attempt to solve:

Simplifying

2a + 3b = 0

Solving

2a + 3b = 0

Move all terms containing a to the left, all other terms to the right.

Add '-3b' to each side of the equation.

2a + 3b + -3b = 0 + -3b

Combine like terms: 3b + -3b = 0

2a + 0 = 0 + -3b

2a = 0 + -3b

Remove the zero:

2a = -3b

Divide each side by '2'.

a = -1.5b

Simplifying

a = -1.5b

Answer 2

Step-by-step explanation:

Question- find product of (5a-2b)(-2a-3b)

Answer:-

5a*(-2a)+5a*(-3b)-2b*(-2a)-2b*(-3b)

-10a^2-15ab-4ab-6b^2

-10a^2-11ab-6b^2
