Question

X=7w^2+4w−6

Y=w^2−11w+13

X+Y=

Answer 1

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.
