Question

10x^2+3x-1 polynomials​

Answer 1

Answer:

X=-1/2,1/5

Step-by-step explanation:

10x^2+3x-1=0

10^2+5x-2x-1=0

5x(2x+1)-1(2x+1)=0

(2x+1)(5x-1)=0

2x+1=0 5x-1=0

X=-1/2 X=1/5

Answer 2

Step-by-step explanation:

for a polynomial of the form ax²+bx+c rewrite the middle term as a sum of two terms whose products is

factor -3 out of -3x

10x²-3(x)-1

rewrite-3as-5+2

10x²+(-5+2)x-1
