4x2 - 3x + 2 - 0 Which of the below shows the correct initial substitution into the quadratic formula.
O, -(3): V(3) ? - 4(4)(2)
2(2)
-(-3) + (-3)2 - 4(4) (2)
2(4)
O
-(2) + V(2)2-4(1)(-3)
= X
2(4)
Ox
-(-3) = V(4)2-4(-3)(2)
2(4)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
