Answer:
Step-by-step explanation:
hello :
(4x+3)(2x-5)=0
4x+3=0 or 2x-5=0
x= -3/4 or x=5/2
(4x+3)(2x-5) = 8x²-14x-15
Step-by-step explanation:
Given,
(4x+3)(2x-5)
To find the value of the given multiplication.
Formula
(a+b)(c+d)
= a(c+d)+b(c+d) = ac+ad+bc+bd
Now,
(4x+3)(2x-5)
= 4x(2x-5)+3(2x-5)
= 8x²-20x+6x-15
= 8x²-14x-15
