Answer:
15x^2-32x+9
Step-by-step explanation:
(3x – 1)(5x – 9)
FOIL
first: 3x*5x= 15x^2
outer: 3x(-9) = -27x
inner: -1(5x) = -5x
last: -1(-9) = 9
Add them together
15x^2 -27x-5x +9
Combine terms
15x^2-32x+9
Answer:
f(x) = 3x(x-1)(x-3)
Step-by-step explanation:
f(x) = 3x³-12x²+9x = 3x(x²-4x+3) =
= 3x(x²-x-3x+3) = 3x[x(x-1)-3(x-1)] =
= 3x[(x-1)(x-3)] = 3x(x-1)(x-3)
Answer:
y = 15x - 10
Step-by-step explanation:
slope is given: 15
(x, y) is given: (1, 5)
plug values into y = mx + b:
5 = (15)(1) + b
solve for b:
b + 15 = 5
b = -10
rewrite the equation:
y = 15x - 10
Answer:
x = -3 and x = 1/2
Step-by-step explanation:
To find the solutions to
2x² + 5x - 3 = 0
we can use the quadratic formula, as follows:
