Answer:
Step-by-step explanation:
The solutions are x=\frac{1+\sqrt{7}}{2} and x=\frac{1-\sqrt{7}}{2}
4s² + <u>14</u>s + 10
4s² + 4s + 10s + 10
2s(2s) + 2s(2) + 5(2s) + 5(2)
2s(2s + 2) + 5(2s + 2)
(2s + 5)(2s + 2)
4s² + <u>22</u>s + 10
4s² + 20s + 2s + 10
2s(2s) + 2s(10) + 1(2s) + 1(10)
2s(2s + 10) + 1(2s + 10)
(2s + 1)(2s + 10)
It could be equal to 14 or 22.
