Answer:
This is an a fake answer but I want to supposed to be multiple pictures?? Because you said add an explanation for each picture and is this history? Are you sure it’s math
Step-by-step explanation:
Answer:
See attached for a "Neat" quadratic formula.
a = -1
b = 2
c = 1
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root(8)] / -2
x1 = (-2 +2.8284271247) / -2
x1 = .8284271247 / -2
x1 = -0.41421
x2 = (-2 -2.8284271247) / -2
x2 = ( -4.8284271247) / -2
x2 = 2.4142135624
So the equation has the positive solution of
2.4142135624

wouldn't it be 24/30%=80 candy bars? thats my answer.
Example -
4x2<span> + 6x + 5</span>
This polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5
The exponent of the first term is 2
The exponent of the second term is 1 because 6x = 6x1
The exponent of the third term is 0 because 5 = 5x0
What? 5x0<span> = 5?</span>
Well, anything with an exponent of 0 is always equal to 1
So, 5x0<span> = 5 × x</span>0<span> = 5 × 1 = 5</span>
Since the highest exponent is 2, the degree of 4x2<span> + 6x + 5 is 2</span>
Answer:
<h2>x = - 3/7 or x = 1</h2>
Step-by-step explanation:
7x² - 4x - 3 = 0
Rewrite - 4x as a difference
That's
7x² - 7x + 3x - 3 = 0
Factorize the expression
7x( x - 1) + 3 ( x - 1) = 0
(7x + 3)( x - 1 ) = 0
7x + 3 = 0 x - 1 = 0
7x = - 3 x = 1
x = -3/7
The solutions are
x = - 3/7 or x = 1
Hope this helps you
