Question

3x^2+7x-10 =0 find value of x​

Answer 1

Answer:

x=1 or x= - √10/3

Step-by-step explanation:

3x^2+7x-10=0

hear we find pair of number which multiplication is 30 and it's pair plus or minus is +7

3x^2+10x-3x-10=0

x(3x^2+10)-1(3x+10)=0

(3x^2+10)(x-1)=0

so x-1=0 or 3x^2+10=0

x=1 or x= - √10/3
