Answer: First option is correct.
Step-by-step explanation:
Since we have given that
[tex]5d^2+4d-3-(2d^2-3d+4)[/tex]
We need to find the correct difference.
Collect the like terms together.
[tex]5d^2+4d-3-(2d^2-3d+4)\\\\=5d^2+4d-3-2d^2+3d-4\\\\=5d^2-2d^2+4d+3d-3-4\\\\=3d^2+7d-7[/tex]
Hence, First option is correct.
Answer:
Option (a) is correct.
[tex]5d^2+4d-3-(2d^2-3d+4)=3d^2+7d-7[/tex]
Step-by-step explanation:
Given: [tex]5d^2+4d-3-(2d^2-3d+4)[/tex]
We have to solve the given expression and choose the correct difference from the given options.
Consider the given expression [tex]5d^2+4d-3-(2d^2-3d+4)[/tex]
Apply plus- minus rule, [tex]-(-a)=a[/tex]
We have,
[tex]=5d^2+4d-3-2d^2+3d-4[/tex]
Adding like terms, we have,
LIKE TERMS are terms having same variable with same degree.
[tex]=(5-2)d^2+(4+3)d-(3+4)[/tex]
Simplify, we have,
[tex]=3d^2+7d-7[/tex]
Thus, Option (a) is correct.
