how do you solve the problem ? 2a(5a-2) + 3a(2a+6) + 8 =a(4a+1) + 2a(6a-4) + 50

Question

need this to be soled help?

Answer 1

2a(5a-2) +3a(2a+6) + 8 = a(4a+1) + 2a(6a-4) + 50

Open the brackets

10a^2 - 4a + 6a^2 + 18a + 8 = 4a^2 + a + 12a^2 - 8a + 50

Collect like terms

10a^2 +6a^2 - 4a^2 - 12^2 + 18a + 8a - a = 50 -8

16a^2 - 16a^2 + 26a - a = 42

26a - a = 42

25a = 42

Divide both sides by 25

25a/25 = 42/25

a = 1.68
