1.
(x-4)(x+2)
(x)(x) + (x)(2) + (-4)(x) + (-4)(2)
x2 + 2x -4x - 8
x2 - 2x - 8
2.If you're looking for the final answer then the answer is:
x - 2
If you're looking for x then the answer is:
x = 2
Explaination:
you should first factor it's the numerator...
( x² - 7x + 10)
(x - 2) (x - 5)
After factoring you could now divide it to x - 5
cancel out x - 5 from both numerator and denominator. Leaving
x - 2 as your final answer.
and x = 2
Answer:
1.x²+6x+8
1.(x+3) (x+5)
Step-by-step explanation:
1.) (x+2)(x+4)
Using foil method...
x²+4x+2x+8
combine like terms..
x²+6x+8
2.) x²+8x+15
find the 2 numbers that when multiplied will result to the last term and when added will equal to the middle term.
in this case its 3 and 5.
3+5=8
3×5=15
now you found the roots.
(x+3) (x+5)=0
x+3=0 x+5=0
x=-3 x=-5
