Answer:
Step-by-step explanation
Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c
3*5=15
Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8
In this Case: - 3*-5=15 and - 3+(-5)= - 8
Step3:
You separate the equation in terms of the two factors you have found
3x^2-3x-5x+5=0
Step 4:Factorise
3x(x-1)-5(x-1)=0
(3x-5)(x-1)=0
Hello, find the work out in the attached image
X = 4.5
Y = -1
Answer:
1/4
Step-by-step explanation:
use PEMDAS first.
P=parenthesis
E=exponents
M= multiplication
D= division
A= addition
S=subtraction
you see a parenthesis so you have to distribute 4 to the variables in the parenthesis. 4 time x is 4x. 4 times 3/2 is 6. after distribution you get 4x+6=7. subtract 6 on both sides. 4x=1. divide 4 on both sides. x=1/4.
