shutvik [7]

The number is 15,
I really don’t know if there’s such a strategy to find this out, I just used trial & error:
(a*4)+(a*3)=35
(5*4)+(5*3)=35
20+15=35

Solve the quadratic equation by factoring 9x2+24+20=4

AnnyKZ [126]

Answer:

Final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .

Step-by-step explanation:

Given equation is $9x^2+24x+20=4$ .

Now we need to solve that by factoring.

$9x^2+24x+20=4$

$9x^2+24x+20-4=0$

$9x^2+24x+16=0$

$9x^2+12x+12x+16=0$

$3x(3x+4)+4(3x+4)=0$

$(3x+4)(3x+4)=0$

$(3x+4)=0$ , $(3x+4)=0$

$3x+4=0$ , $3x+4=0$

$3x=-4$ , $3x=-4$

$x=-\frac{4}{3}$ , $x=-\frac{4}{3}$

Hence final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .
