Answer:
here is your answer mate...
Step-by-step explanation:
√2x+9 + x = 13
√2x+9 = 13-x
squaring both sides
2x + 9 = (13-x)²
2x+9 = 169 - 26x + x²
2x +26x +9 - 169 = x²
28x-160 = x²
by using factorization method
x²-28x+160 = 0
x² - 20x - 8x +160 = 0
x(x-20) -8(x-20) = 0
(x-20)(x-8) = 0
x = 20 and x= 8
plz plz plz mark me as brainliest plzz...
