Use the formula for finding axis of symmetry:
-b -25 -25
x = ------ ⇒ --------- = -------- = 2.6
2a 2(-4.9) -9.8
7y^2 + 10y + 3
7y^2 + 7y + 3y + 3
(7y^2+7y) + (3y+3)
7y(y+1) + 3(y+1)
(7y+3)(y+1)
So the final answer is <span>(7y+3)(y+1)</span>
Answer:
/
Step-by-step explanation:
firstly we make two steps to simplify this question.
1st step: simplify 
to simplify this we use factorization


.....(1)
2nd step:simplify 


.....(2)
now dividing (1) and (2), we get the answer
