Answer:
the answer is B x= -4/3
Step-by-step explanation:
9x^2+24x+20=4
9x^2+24x+20-4=0
9x^2+24x+16=0
(3x+4)^2=0
3x+4=0
3x=-4
x= -4/3
Answer:
(x + 3)(2x + 5)
Step-by-step explanation:
Given
2x² + 6x + 5x + 15 ← grouping the terms
= (2x² + 6x) + (5x + 15) ← factor each group
= 2x(x + 3) + 5(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x + 5) ← in factored form
