<h2>Using the quadratic formula</h2>

The quadratic formula can help us solve for x in a quadratic equation:

$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$

We can use this when the given equation is organized in standard form: $ax^2+bx+c=0$

<h3>Applying this to the problem</h3>

$2x^2+5x-4=0$

First we can identify the values of a, b and c:

a = 2

b = 5

c = -4

Plug these values into the quadratic formula:

$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$

$x=\dfrac{-5 \pm \sqrt{5^2-4(2)(-4)}}{2(2)}$

$x=\dfrac{-5 \pm \sqrt{25+32}}{4}$

$x=\dfrac{-5 \pm \sqrt{57}}{4}$

<h2>Answer</h2>

Therefore, the two possible values of x are:

$x=\dfrac{-5 +\sqrt{57}}{4}$

$x=\dfrac{-5 -\sqrt{57}}{4}$

Grace needs to buy a new printer. The printer she wants has a price tag of $60. She has a 25% off coupon and $50 in her bank acc

aleksklad [387]

Answer:

Yes, she will have $1.96 left

Step-by-step explanation:

Initial cost : $60

Discount : 25%=0.25

Calculating discount : 60 * 0.25 = 15

Calculating cost after discount : 60-15 = 45

Sales tax : 6.75%=0.0675

Calculating sales tax : 45 * 0.0675 = 3.0375≈$3.04

Calculating final cost : 45+ 3.04 = $48.04

Can she buy the printer : 50 - 48.04= $1.96

Answer : yes
