( x + 5 ) and ( x – 2 )
You can factor the above binomial and solve for zero. You'll have x^2 + 5x – 2x – 10, which simplifies to your original x^2 + 3x – 10
Answer:
27 3/32
Step-by-step explanation:
Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
Answer:
15x + 16
Step-by-step explanation:
open parentheses
6x + 7 + 9x + 9
combine like terms
6x + 9x + 7 + 9
15x + 16
The Answer is (6x^2+7x+2)
Use the FOIL method
