isoke is solving the quadratic equation by completing the square. 10x²+40x - 13=0 10x²+40x=13 a(x²+4x)=13 what is the value of a? -13 4 10 40
Answer
Explanation:
Step1: Factor out the coefficient of $x^{2}$
We start with $10x^{2}+40x = 13$. We can factor out 10 from the left - hand side terms $10x^{2}+40x$ to get $10(x^{2}+4x)$. So, $A = 10$.
Answer:
10
