The expression which correctly sets up the quadratic formula to solve the equation is (A) \frac{-(-4)+-\sqrt[]{-4^{2}-4(1)(3) } }{2(1)}.

What is an expression?

  • In mathematics, an expression is a combination of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)
  • Expressions are similar to phrases.
  • A phrase in language may comprise an action on its own, but it does not constitute a complete sentence.

To find which expression correctly sets up the quadratic formula to solve the equation:

Theory of quadratic equation - A quadratic equation is defined as any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

An example of a quadratic equation in x is -4x^{2} +4=9x.

How to solve any quadratic equation using the Sridharacharya formula?

Let us represent a general quadratic equation in x, ax^{2} +bx+c=0 where a, b and c are coefficients of the terms.

According to the Sridharacharya formula, the value of x or the roots of the quadratic equation is -

x=\frac{-b+-\sqrt{(b)^{2}-4(a)(c) } }{2a}

The given equation is x^{2} -4x+3=0

Comparing with the general equation of quadratic equation, we get a = 1, b = -4 , c = 3.

Putting the values of coefficients in the Sridharacharya formula,

\frac{-(-4)+-\sqrt[]{-4^{2}-4(1)(3) } }{2(1)}  which is (A).

Therefore, the expression which correctly sets up the quadratic formula to solve the equation is (A) \frac{-(-4)+-\sqrt[]{-4^{2}-4(1)(3) } }{2(1)}.

Your brother has saved $60 to spend on basketball cards he plans to by the cards at a sale single card is $9 and if u buy three
schepotkina [342]

Answer:

7 cards.

Step-by-step explanation:

60-39.5=20.5, that's what he has left if he buys 5 cards.

so, if you buy 2 more cards, that would be 18 dollars so 20.5-18=2.5

5 cards+ 2 cards= 7 cards.

He still hzs 2.5 dollars left

Review the steps of the proof of the identity
koban [17]

Answer:

step 2

and then also in step 3 compensating the error in step 2

Step-by-step explanation:

I think I just answered this for another post.

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

so, step 1 is correct :

sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)

but step 2 suddenly and incorrectly switched that central "-" to a "+".

yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.

then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.

4 + 9 + (16 ÷ 4 - 8 - 3) × 5

= 13 + (4 - 8 - 3) × 5

= 13 - 7 × 5

= 13 - 35

Simplify the expression. (x1/6 y1/9)3
harina [27]
Ok, first let's multiply:
3 x 1/6 = 3/6 (simplify:) 1/2

Then multiply again:
3 x 1/9 = 3/9 (simplify:) 1/3

Now the expression is simplified to (1/2x, 1/2y)

Hope this helped! Please comment or DM me if you have anymore questions or don't understand :)
