Question

MATHEMATICS
1. Using completing the square method : (i)
${4x}^{2} + 10x - 5 = 0$
​

Answer 1

Answer:

16x^4 + 80x^4 + 100x^2 = 25

Step-by-step explanation:

4x^2 + 10x = 5

Squaring both sides,

(4x2 + 10x)^2 = 5^2

(4x2)^2 + (10x)^2 + 2(4x2)(10x) = 25

16x^4 + 100x^2 + 80x^3 = 25

16x^4 + 80x^4 + 100x^2 = 25
