Answer:
Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
So what you want to do is do long division (using 32.000 divided by 1243.12). You should get this answer:
0.02574
Hope this helped
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
√4 + √16 = 2 + 4 = 6 <--- rational
√5 + √36 = √5 + 6 <--- irrational
√9 + √24 = 3 + √24 <--- irrational
2 * √4 = 2 * 2 = 4 <--- rational
√49 * √81 = 7 * 9 = 63 <---rational
3√12 = 3√(4 * 3) = (3 * 2)√3 = 6√3 <---irrational
Hope this helps ^-^
