First you replace the letters with the numbers: n = 9, z = 2.

9 + (16 - 2³) ÷ 2

2³ = 8
(16 - 8) = 8
8 ÷ 2 = 4
9 + 4 = 13

Divide using any method 2x^2+5x+1 ÷ X+3​
Natali [406]

Question:

Solve the equation 2x2−5x+3=0 by the method of completing square.

Answer:

We have,

2x2−5x+3=0

⇒x2−25x+23=0 (Dividing throughough by 2)

⇒x2−25x=−23 (Shifting the constant term on RHS)

⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)

⇒(x−45)2=1625−23⇒(x−45)2=16

How do you turn slope into intercept form into standard form
Jet001 [13]
Assuming you already have your slope. Let’s assume you have a slope of 3/4. (m=3/4)

Slope intercept form is y=mx+b
y and x being a point
m is your slope
and b is your y-intercept
So for example, you have a y-intercept of 3, your equation would be y=3/4x+3

Standard form is Ax+By=C
