The answer is the the second one
Answer:
(a - 2) • (3a - 4)
Step-by-step explanation:
(3a2 - 10a) + 8
Trying to factor by splitting the middle term
2.1 Factoring 3a2-10a+8
The first term is, 3a2 its coefficient is 3 .
The middle term is, -10a its coefficient is -10 .
The last term, "the constant", is +8
Multiply the coefficient of the first term by the constant 3 • 8 = 24
Find two factors of 24 whose sum equals the coefficient of the middle term, which is -10 .
-24 + -1 = -25
-12 + -2 = -14
-8 + -3 = -11
-6 + -4 = -10 That's it
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -4
3a2 - 6a - 4a - 8
Add up the first 2 terms, pulling out like factors :
3a • (a-2)
Add up the last 2 terms, pulling out common factors :
4 • (a-2)
Add up the four terms of step 4 :
(3a-4) • (a-2)
Which is the desired factorization
Final result :
(a - 2) • (3a - 4)
Answer:
=−30x−62
Step-by-step explanation:
Distribute:
=−3+(−3)(2x)+(−3)(7)+(−4)(6x)+(−4)(7)+−10
=−3+−6x+−21+−24x+−28+−10
Combine Like Terms:
=−3+−6x+−21+−24x+−28+−10
=(−6x+−24x)+(−3+−21+−28+−10)
=−30x+−62
Answer:
=−30x−62 i think :)
