Question

how much is 2a -3a greater than 2a square+4a

Answer 1

2a-3a= -a
= 2a
$2a {}^{2} + 4a = 0 \\ = 2a(a + 2) = 0 \\ = a + 2 = 0 \\ a = - 2$
a= -2
2a = 2×-2 = -4

Answer 2

Hello mate

here's your answer

_______________

First of all keys find the value of
=>2a-3a
=>-a
The value of
${2a}^{2} + 4a$
would remain same.

Then if we subtract both the numbers than we will get the greater.
${2a}^{2} + 4a - ( - a) \\ \\ {2a}^{2} + 4a + a \\ \\ {2a}^{2} + 5a$
