Answer:

B)y = 3x^2 - 3x-18

Step-by-step explanation:

y = (3x – 9)(x + 2)

y = 3x*x+3x*2-9*x-9*2

y = 3x^2 +6x-9x-18

y = 3x^2 - 3x-18

What are the solutions to 3x^2 = 8x — 6?
Bond [772]

Answer:

First, let's move all terms to one side,

\sf x^2-8x+6=0

When given this form (ax^2+bx+c=0), there will be two solutions at the end.

1) \sf x=\frac{-b+\sqrt{b^2-4ab} }{2b}

2) \sf x=\frac{-b-\sqrt{b^2-4ab} }{2b}

where, a=1, b=-8, c=6

\sf x=\frac{8+\sqrt{(-8)^2-4\times6} }{2} ,\frac{8-\sqrt{(-8)^2-4\times6} }{2}

Simplify,

\sf x=\frac{8+2\sqrt{10} }{2} ,\frac{8-2\sqrt{10} }{2}

Simplify,

\sf x=4+\sqrt{10}, 4-\sqrt{10}

Hope it helps!
