Question

factorize the following​

Answer 1

Answer:

(a - 20)(a + 30)

Step-by-step explanation:

We have

a^2 + 10a - 600

-600 = 30 * -20

10 = 30 - 20

So, we can write eqn as

a^2 + 30a - 20a + (30)(-20)

a(a+30) - 20(a + 30)

(a - 20)(a + 30)

Answer 2

Answer:

with step by step explanation

$a {}^{2} + 10a - 600 = 0$

$a {}^{2} + 30a - 20a - 600 = 0$

$a(a + 30) - 20(a + 30) = 0$

$(a - 20)(a + 30) = 0$

hence factorised
