Question

2√28-√75-1/√3 step by step
​

Answer 1

Answer:

STEP BY STEP

Step-by-step explanation:

The first term is, x2 its coefficient is 1 .

The middle term is, -28x its coefficient is -28 .

The last term, "the constant", is +75

Step-1 : Multiply the coefficient of the first term by the constant 1 • 75 = 75

Step-2 : Find two factors of 75 whose sum equals the coefficient of the middle term, which is -28 .

-75 + -1 = -76

-25 + -3 = -28 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -25 and -3

x2 - 25x - 3x - 75

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

x • (x-25)

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

3 • (x-25)

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

(x-3) • (x-25)

Which is the desired factorization

Equation at the end of step

1

:

(x - 3) • (x - 25) = 0
