Answer:
1. c
2. a
3. a
Step-by-step explanation:
first we need to multiply it (2x – 1)(x + 3) = 0
remember the FOIL method; F-first term (2x)(x), O-outer term (2x)(3), I-inner term (-1)(x), ang L-last term (-1)(3). Multiply the terms, we have 2x^2 +6x-x-3= 2x^2+5x-3
remember the standard form of writing quartic equation. ax^2+bx+c=0.. so a=2, b=5 and C=-3
10x^2 – 3x – 20 = 0
just follow the standard form in order to identify a, b and c
6x^2 + 2 = 0
follow the standard form. since their is no value of x, so b=0
