Answer:
10x^2 (x+2) (x+6)
Step-by-step explanation:
assuming you meant 120 not 1120
10x^4+ 80x^3 + 120x^2
factor out 10 x^2
10x^2 (x^2 +8x+12)
what numbers multiply together to get 12 and add together to get 8
2*6 = 12 2+6 = 8
10x^2 (x+2) (x+6)
B and D are the same answer?????
Well if u think about it 2x3=6, 5x2=10,8x2=16, so pretty much what u are doing u are multiplying by 2
Answer:
Step-by-step explanation:
(1x/4 + 1/7) + (3x/8 - 1/3) = x/4 + 3x/8 + 1/7 - 1/3
= x*2/4*2 + 3x/8 + 1*3/7*3 - 1*7/3*7
= 2x/8 + 3x/8 + 3/21 - 7/21
= (2x+3x)/8 + (3-7) /21
= 5x/8 + (-4)/21
= 5x/8 - 4/21
Answer:
x = - 10
Step-by-step explanation:
Given
10 - x = - 2x ( add 2x to both sides )
10 + x = 0 ( subtract 10 from both sides )
x = - 10
