I use the railroad method so here's how I would solve it:
4 x 25 = 100
10 x 10 = 100, 10 + 10 = 20
(x +10/4)(x + 10/4)
(x + 5/2)(x + 5/2)
The answer should be: (2x + 5)(2x + 5)
It can be checked:
2x x 2x = 4x^2
2x x 5 = 10x
5 x 2x = 10x
5 x 5 = 25
4x^2 + 20x + 25
So yes, the answer would be (2x + 5)(2x + 5)
h(x) = 3x + 5
h(a) = 27
We can write this as 3a + 5 = 27
Now, we just need to solve for a.
<em><u>Subtract 5 from both sides</u></em>
3a = 22
<em><u>Divide 3 from both sides.</u></em>
a = 7.33
Now, let's plug 7.33 back into the original equation.
3 * 7.33 + 5 = 27
22 + 5 = 27
27 = 27 √ this is correct
