Answer:

$18x^2-30x+8$

Step-by-step explanation:

The given equation is:

$(3x-4)(6x-2)$

Simplifying the above given expression using FOIL that is the standard method of multiplying two binomials, we get

⇒ $3x(6x)-4(6x)-2(3x)+4(2)$

⇒ $18x^2-24x-6x+8$

⇒ $18x^2-30x+8$

which is the required simplified form of the given expression.

−8x + 4y = 24 -- (1)
−7x + 7y = 28 -- (2)

Eqn (1) & (2) are simplified as

y - 2x = 6 -- (3)
y - x = 4 -- (4)

By making y the subject of formula in (4), we have

y = x + 4 -- (5)

Substitute x + 4 for y in (3), then

x + 4 - 2x = 6
x - 2x = 6 - 4
- x = 2
x = - 2.

Substitute - 2 for x in (5), then

y = - 2 + 4
y = 2.

Therefore, (x, y) = (- 2, 2) ...Ans.

Answer:

a). 8(x + a)

b). 8(h + 2x)

Step-by-step explanation:

a). Given function is, f(x) = 8x²

For x = a,

f(a) = 8a²

Now substitute these values in the expression,
