Question

Solve by using square root property of 322×324/323^2-1​

Answer 1

Answer:

The first term is, x2 its coefficient is 1 .

The middle term is, -2x its coefficient is -2 .

The last term, "the constant", is -323

Step-1 : Multiply the coefficient of the first term by the constant 1 • -323 = -323

Step-2 : Find two factors of -323 whose sum equals the coefficient of the middle term, which is -2 .

-323 + 1 = -322

-19 + 17 = -2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -19 and 17

x2 - 19x + 17x - 323

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-19)

Add up the last 2 terms, pulling out common factors :

17 • (x-19)

Step-5 : Add up the four terms of step 4 :

(x+17) • (x-19)

Which is the desired factorization
