f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
Answer:
2 hours=120minutes
120minutes÷5=24
24 pages he can read in two hours
Answer:
x = -3
Step-by-step explanation:
What you do is get x by itself.
1/4(8x - 4) = 5x + 8 <u>Distribute 1/4 to 8x and -4.</u>
2x - 1 = 5x + 8 <u>Subtract 5x on both sides.</u>
-3x -1 = 8 <u>Add -1 to both sides.</u>
-3x = 9 <u>Divide -3 on both sides.</u>
x = -3
