What are the solutions to 3x^2 = 8x — 6?

Mathematics

Bond [772]2 years ago
5 0

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!

When q = 15, r = 4<br> Find q when r = 7
djyliett [7]

Answer:

q = 18 ?

Step-by-step explanation:

This is not a complete question but ill give it a shot!

If we are following a pattern then we see q is 11 more than r.

So we do 11 + r (7) to get 18!

What is the Pythagorean Theorem used for? What is the formula
saveliy_v [14]
The Pythagorean Theorem states that a triangle's hypotenuse is equal to the square's of the other two sides of the triangle.

a² + b² = c<span>²
a = side of triangle
b = other side of triangle
c = hypotenuse (squared)

Find the square root to find the accurate length of the hypotenuse.</span>
