Question

7X square + 4 x - 3​

Answer 1

Step-by-step explanation:

The first term is, 7x2 its coefficient is 7 .

The middle term is, -4x its coefficient is -4 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 7 • -3 = -21

Step-2 : Find two factors of -21 whose sum equals the coefficient of the middle term, which is -4 .

-21 + 1 = -20

-7 + 3 = -4 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 3

7x2 - 7x + 3x - 3

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

7x • (x-1)

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

3 • (x-1)

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

(7x+3) • (x-1)

Which is the desired factorization

Answer 2

Answer:

7×-4/4 =3

Step-by-step explanation:

7×-1 =3 7×=3+1 7×=4 ×=4/7
