Answer: 16x+3+x214
Step-by-step explanation:
Multiply 2 and 2 to get 4.
4+16x+x214−1
Subtract 1 from 4 to get 3.
3+16x+x214
To add or subtract expressions, expand them to make their denominators the same. Multiply 3+16x times x2x2.
x2(3+16x)x2+x214
Since x2(3+16x)x2 and x214 have the same denominator, add them by adding their numerators.
x2(3+16x)x2+14
Do the multiplications in (3+16x)x2+14.
x23x2+16x3+14
