If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
Answer:
= 7/2
Step-by-step explanation:
−
7a ^2 - a^2 + 16
7a^2 - a^2 + 16 = 6a^2 + 16
7a^2 - a^2 + 16
6a^2 + 16
Answer:
f(x) = x^2 (x + 7i)(x - 7i)
Step-by-step explanation:
Factoring out x^2 gives ...
f(x) = x^2(x^2 +49)
The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...
x^2 +49 = (x +7i)(x -7i)
So, the overall factorization of f(x) is ...
f(x) = x^2(x +7i)(x -7i)
