Answer:
(3x+4)(2x−5)
Step-by-step explanation:
The first term is, 6x2 its coefficient is 6 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -20
Step-1 : Multiply the coefficient of the first term by the constant 6 • -20 = -120
Step-2 : Find two factors of -120 whose sum equals the coefficient of the middle term, which is -7 .
-120 + 1 = -119
-60 + 2 = -58
-40 + 3 = -37
-30 + 4 = -26
-24 + 5 = -19
-20 + 6 = -14
-15 + 8 = -7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 8
6x2 - 15x + 8x - 20
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (2x-5)
Add up the last 2 terms, pulling out common factors :
4 • (2x-5)
Step-5 : Add up the four terms of step 4 :
(3x+4) • (2x-5)
Which is the desired factorization
Answer:
(x,y)=(2,0)
Step-by-step explanation:
Use the first equation to find x. add 1/6 y on both sides, then multiply by 6/5 to get x by itself.
you will get x=2+1/5y
Now you substitute the x value into the second equation
1/2(2+1/5y)+3/4y=1
Distribute the 1/2 to get
1+1/10y+3/4y=1
The only possible value for y is 0.
Now you know y = 0.
Now substitute 0 in for the y in the x value
x = 2+1/5y
x=2+0
x=2
Therefore your answer is <u>(2,0) or x=2 y=0</u>
