X + Y = 8w² - 7w + 7
Step-by-step explanation:
Given that,
X = 7w² + 4w - 6
Y = w² - 11w + 13
We have to find X + Y = ?
Now, X + Y
= (7w² + 4w - 6) + (w² - 11w + 13), putting the values of X and Y
= 7w² + 4w - 6 + w² - 11w + 13, opening the brackets
= 7w² + w² + 4w - 11w - 6 + 13, rearranging the like terms
= (7 + 1) w² + (4 - 11) w + (- 6 + 13), by grouping the like terms
= 8w² - 7w + 7
This is the required sum.
