5A2 + 3 = 48 Therefore, 5A2 = 45 Therefore, A2 = 45/5 A = sqrt(9) A = 3
If you mean: 5a2+24a-5 then it is (5a-1)(a+5) when factored
(5a + 2)(a + 1)
4a - 5a^2
5a2*1/6 = (5/6)a2
It is: 5a2
5a x a = 5a2
5a2 + 6ab=a(5a+6b)
solving by factoring 5a2
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
"tan times 5A2" makes no sense.
(5a2 - 3)(5a2 + 3)
In rationalising quadratics 2a3 - 5a2 - 39 is an irrelevance. It is not a quadratic but a cubic and so not within the defined scope.
5(a2-3)
5A2 + 3 = 48 Therefore, 5A2 = 45 Therefore, A2 = 45/5 A = sqrt(9) A = 3
If you mean: 5a2+24a-5 then it is (5a-1)(a+5) when factored
8a(5a2-1)
