AnSwer This qudratic equation​

Answer 1

Answer:

Step-by-step explanation:

a) (2x-3)(3x+1) = 0

x = 3/2 or -1/3

b) 3x^2 - 243 = 0

3x^2 = 243

x^2 = 243/3

x^2 = 81

x =sqrt 81

x = +9 or -9

c) x^2+6x+5=0

x^2+5x+x+5 = 0

x(x+5) + 1(x+5) = 0

(x+1)(x+5) = 0

x = -1 or -5

d) x^2 + 12x +35 = 0

x^2 + 7x + 5x + 35 =0

x(x+7)+5(x+7)=0

x=-5 or -7
