Question

7y to the power 4 - 25y square + 12 =0​

Answer 1

Answer:

Below is your answer....

Explanation:

Step by step solution :

Step-1 : Multiply the coefficient of the first term by the constant 7 • 12 = 84

Step-1 : Multiply the coefficient of the first term by the constant 7 • 12 = 84 Step-2 : Find two factors of 84 whose sum equals the coefficient of the middle term, which is 25.

Step-3 : Add up the first 2 terms, pulling out like factors :

: Add up the first 2 terms, pulling out like factors : y2 • (7y2+4)

: Add up the first 2 terms, pulling out like factors : y2 • (7y2+4) Add up the last 2 terms, pulling out common factors :

: Add up the first 2 terms, pulling out like factors : y2 • (7y2+4) Add up the last 2 terms, pulling out common factors : 3 • (7y2+4)

Step-4 : Add up the four terms of step 4 :

: Add up the four terms of step 4 : (y2+3) • (7y2+4)

: Add up the four terms of step 4 : (y2+3) • (7y2+4) Which is the desired factorization
